Who would win?. I think both are equally deadly (and hottt!). Personally, I rather Huntress to be the winner, but Elektra is pretty much skilled, both of them could perfectly win the match.
"does huntress use the same,gadgets like batman? if so she wins? with version of huntress are we using? is this one where she uses crossbows/guns maybe the version where she is batman(batwoman) "
Fully equiped Huntress. With crossbows... but let's forget about guns (I think crossbows are more than enough)!. Anyway, I think you're underestimating Huntress, she is perfectly able to beat the hell out of Elektra... at least she would be a better match for Elektra instead of Catwoman (in my opinion)
