Maybe it's because I grew up on Bruce Timm cartoons but I've never really considered Hackman to be that great of a Lex. He was entertaining as hell sure but not really "Lex Luthor: Nemesis of Superman" to me. Spacey was okay but still not there. At least he came of as somewhat threatening. Eisenberg (as of now) comes off as an over-the-top weirdo trying to be a cartoon character. BUT Just like Leto as the Joker I'm waiting to see the movie before I really start judging. I wasn't really a fan of him in the Suicide Squad trailer but the movie looks good (so does Dawn of Justice) so I'm waiting to see how he is in it.

Lex from the DCAU will always be the definitive Lex for me just like DCAU Joker is the definitive Joker. And it doesn't hurt that Lex is voiced by Clancy Brown and he's awesome.
