I always liked the post-crisis Luthor. A corrupt billioniar always made more sense to me then a mad scientist. I understand what you say about Batman, and Frank Millar tried to explain that these two would have vastly different worldviews given what shaped who they are. I guess that's hard to argue with regardless of whether or not you like it. Another thing I liked is the fact that they got rid of the different varieties of kryptonite. One that can kill him is enough.
I agree about luthor His motivations just seemed better to me. Less kryptonite is better too. I think post crisis went a little to far with Batman/ Superman at times but the Recent Worlds Finest run worked pretty well. Big Surprise,I liked the TAS take better.I also enjoy the less omnipotent versions of everyone early on. I just wish there had been less throw out the baby with the bath water.
Less kryptonite and vastly depowering Superman along with his villians was a huge mistake. In a way, it's quite funny that DC editorial accomplished exactly the opposite of what they set out to do. The Iron Age Superman simply had no physical challenge before Doomsday.
Mongul was made into a complete wuss who got smacked around by a depowered Superman as opposed to the PC version which could take whatever Supes could throw at him and come back for more. Superman only defeated him after pulling out all stops and passed out shortly afterwords. And this was after Mongul had trashed the Justice League (inlcuding Supergirl) and briefly skirmished the LOSH. Another annoyance due to this was Darkseid being shoved into many stories.
Bizarro only appeared in a couple of stories before Emperor Joker brought him back full time.
The PU Zod was depowered to the point of being a joke.
Daxamite villians were out of the picture because of lead.
All of this nonsense is what led to 20 long years with the Kingpin ripoff.
