Batman also has access to the Insider Suit: http://batman.wikia.com/wiki/Insider_Suit
It's a suit that grants the wearer temporary access to flight, various modes of vision, as well as heat vision, the speed force, energy blasts akin to those of Green Lanterns, camouflage, teleportation, and an cord that acts like Wonder Woman's magical lasso.
Batman in his present time already has a suit that's just as lethal, if not more so, than Terry's Batman Beyond suit, which is literally decades ahead of even its own futuristic era. Even then, Batman has access to mechanized military weapons as this anon pointed out: >>84584104
Yeah, I realize Parker now has his own company, and is wealthy now too. But I really doubt his resources are on par with the Wayne Family. Only Lex Luthor is on par with Wayne in terms of wealth and access to technology, while Parker probably doesn't even matches Stark.
