Who is the most skilled in....

What characters do you think are the most skilled or experienced in each of these areas/fields. You can pick two characters if both are nearly on par with one another in that field.

Tactics/strategist/leader:

Espionage:

Computers/hacking:

Detective Skills:

Technology:

Bio/Chem/Physics:

Tracking:

Acrobatic:

Engineering:

Survival skills:

Batman

I'll pick one from DC and one from Marvel for each

Tactics/strategist/leader: Batman/Captain America

Espionage: Batman/Black Widow

Computers/hacking: Oracle/Iron man?

Detective Skills: Batman/Daredevil

Technology: Lex Luthor/Iron man

Bio/Chem/Physics: Lex Luthor/Reed Richard

Tracking: Superman (Based on his superhuman senses)/ Wolverine-Daredevil-Kraven (Different areas)

Acrobatic: Nightwing/Daredevil (Spiderman is better but is superhuman)

Engineering: Lex Luthor/Iron man

Survival skills: Hard to define

But really,

Luthor and Stark are best at technology. Dick Grayson and Selina Kyle are better acrobats. Tracking goes to Wolverine; not going to include extremely powerful characters. Engineering: not sure. Reed, Luthor, Stark, Pym...

The others, I would choose Batman

Tactics/strategist/leader: Captain America is the best leader, Batman has better tactics/strategies but is too uncharismatic

Espionage: Martian Manhunter should, but someone like Nightcrawler actually use their abilities for it more

Computers/hacking: Cyborg!

Detective Skills: Batman

Technology: Tony Stark

Bio/Chem/Physics: Reed Richards or maybe Ray Palmer or Hank Pym.

Tracking: Wolverine

Acrobatic: Daredevil, Dick Grayson, Nightcrawler, Spider-man, Beast up there too

Engineering: Dr. Doom or Lex Luthor , but I'd throw in Qubit from Irredeemable

Survival skills: kinda hard to call this one. Not sure on the parameters...

Tactics/strategist/leader: Batman or Captain America

Espionage: SHIELD

Computers/hacking: Ultron

Detective Skills: Batman

Technology: Tony Stark

Bio/Chem/Physics: Reed Richards

Tracking: Goku

Acrobatic: Spider Man

Engineering: Dr Doom

Survival skills: Big Boss

Harley Quinn >>> Nightwing/Catwoman

@joygirl: I like Harley to death but I'm not sure if she's better than Catwoman. She is better than Batman though

This.

@joygirl: okay you may be right haha. I remember that from Hush

This is only for the DC Universe as I do not really read Marvel
