No, feel free to go with whatever.
I think I would personally consider both superheroes myself as both can compete with those with powers far beyond the capabilities of regular humans, in part due to gadgets, but also having great minds.
If they can hold their own with super powered beings, I think they've earned themselves the title of superhero.
Batman only fights people with mental disorders! He never went against someone/something with actual super powers.
All this suggests to me is that you have a very selective knowledge of Batman.
Eventually the world's military will have things that surpass his suit.
And who's gonna build it? Someone else is working on an arc reactor right now? Inventing a new element? Stark has that technology now, when it's needed, not "eventually".
Raven was always my favorite back when I used to watch Teen Titans. I don't really know much about her in the comics, but in the show I found her relatable and interesting. The romance thing with Robin was weird to me too. I think she may be the only DC character besides Batman that I remotely like.
