Pre-resi 5 Jill, obviously. Any other answer is clearly wrong. I mean, she's the master of unlocking, man. She's awesome in Revelations as well. I thought the resi3 remake version of Jill wasn't as good, however. She was TOO badass and kept cracking one-liners all the time when she was in imminent danger.
If we are including side characters (not counting Gaiden and revelations 2 because I wasn't that keen on him there), I'll have Barry for resi 1 lines alone. And I hear he makes a great Sandwich.
I like Claire too, so she'd be my next pick for RE2 and CV which I really liked her in. I also liked her in revelations 2 as well. I thought she was quite good in the resi 2 remake as well, except they make her too badass again like they do with Jill in resi 3 remake.
Ada is probably next - I really like her DLC in 4 and story in 6. She's good in 2 as well just because she's mysterious.
Leon, should never have been the last action hero for me, but I liked him as rookie cop in the original resi 2 and the remake. He was ok in 4, too badass again for me in a survival game.
Chris is my next pick because I while I liked him in resi 1 and CV, he was just annoying as a character from 5 onwards and he is in a lot of them.
Maybe Rebecca and Billy next? I mean they just are only protagonists in one game so they are lower of the list from that alone. I think I'd take billy over Rebecca.
Jake is just a pointless addition in my eyes. Sherry is OK, but she gets marks deducted for being in Jake's story.
I've probably missed some out but...
