Who's better at building Tech? Bruce Wayne or Tony Stark

Stark is better with tech. Bats has some impressive technological accomplishments, such as building teleport terminals, engineering mechanized power suits, constructing transmutation nanites, building/maintaining his super computer (which is only used for basically everything, using plot-filled databanks, holographic projections, and system supports), preparing the numerous devices in his belt, helping to rebuild Red Tornado's body, and many other tech feats. Stark, however, is more dedicated and refined in this though. Batman's knowledge is more broad, I think, than Tony's is, and he has less of a focus on engineering technology than Tony does. Stark makes constant upgrades to his armors, using gravitational, magnetic, repulsor, and shielding tech in his suits. He has used nanite technology and built time machines as well. So, Iron Man for the win.

In Avengers Prime, used some medieval instruments to re-build his armour.
 
I remember reading FF and Reed Richards stated explicitly that Stark is a better engineer than him.
 
While i believe that Bruce is richer (Norman Osborn and the American government pretty much ruined Stark after Secret Invasion) and is overall smarter, i believe that Tony is better with tech. It's just his thing.

Tony has better tech than Bruce but Bruce is better with prep.

" @deathlife: i think bruce holds back, because  as i mentioned earlier when bruce doesnt hold back its Bruce gone wild, and he can make unbelievable  Tech..
@Achilles.:  when tony is building something  thats prep ,  so Bruce would be on par with Stark, but Tony can throw down some gadgets that would scare any marvel or DC character, love to see a superman buster armor lol "

"@TheBatman586: Is that superman/batman?If so then i'd be cautious of using this. He built some JLA drones which were capable of mimicking their powers in JLA classified ,but on the downside they got owned by grodd,quite easily.  "

" @Susanoo:  Invincible Iron Man #25. Stark went to Reed Richards for help to build his new armor. Stark mentioned that the reboot wiped out all his minds basic functions, reed then commented that stark could now use his full control over his body and mind, as well as his enhanced brainpower, to operate the suit. Reed kinda indicated that starks brain has gone from impressive, to "oh my god that thing should be enormous" level. "

" @franklinrichards86: thats more like it  but any thing current?"

Stark has way better tech. Hulkbuster, Thorbuster, Extremis. Nothing Bats has made compares to these armors. Not to mention Bruce usually depends on reverse engineering and the help of others, while Tony largely invents and comes up with things on his own.

Stark has far superior tech building feats , i'd say he's quite a bit more intelligent also  in JLA/Avengers crossover Bruce even says how he thought a job that would take him days was done in hours by Tony.  
 
Tony is more of a tech master where as Bruce is more of a jack of all trades being educated well in many things , more than Tony but in tech Tony is far superior. 

Brce is richer right now probably but theres no way of knowing.

 
I don't really care who the ultimate playboy is

Im with Stark on the tech building but to 2nd Erik he is broke so bruce is the better playboy.

Stark

" Tony is better at building it... Bruce is better at running a company. "

" @TheBatman586:  Superman/Batman is only sometimes canon. They are basically writing whatever they want for the series and some fits and some does not. Actually, as far as I know, the only story that is for sure canon is the Supergirl arc.  "

" @erik:  i know. he needed help to build it, not design it. after all, its hard to build stuff when all your facilities were destroyed fighting zeke stane lol "

Everything up until the arc involving Orion's wife and Darkseid is canon too.  A lot of S/B's early years are all canon. "

Iron Man wins hands down.

Stark has been building and designing tech since he was a kid... He easily wins this one... although yes Bruce is better at running a company...

I would not go as far as to say Bruce runs a company better. He has a less active role in his business than Tony ever did (except maybe when Tony was going through his demon in a bottle thing).  
 
Before his company was shut down, it was on the road to being the absolute first in medical tech and research. Plus the consumer market was dominated by his products. 

Stark.

" @franklinrichards86: well wayne tech is still broader as of now, and  tonys  hulk buster  didnt do anything in World war Hulk, and his tech failed  in the skrull invasion.....tuff few years for Stark "

• Hulk was just a great deal stronger than what Stark had anticipated. 
• Key word: Skrulls. Any Wayne tech that was networked would have failed as well. 
• Start invented just about everything S.H.I.E.L.D. uses. Their tech and Stark tech was all networked into the Stark Data Spine. An alien virus infiltrated it and wiped it. 

" @Morpheus_:  Did not know about the sabotage. Well that just makes Tony THAT much better. "

Tony for the win here.

Bruce has more overall knowledge than Tony, yes. But when it comes to Tech Tony>>>>>>>>Bruce. "

It seems like over bruce's life he has built a lot of the same stuff tony has, but more.  In the justice league he has to get all kinds of things to work, and when he is old man bruce, he builds robots to help him be batman.

" @erik: the punisher  was able to get past  Stark tech and take a deal of weapons and equipment in  civil war. Bruce would be  far more fortified then that "

bleeding edge armor (aka extremis mk 2)
