i like them both, but the oval-less bat makes no damn sense. it has no reason to exist on any costume.
but that is by in large the way the suit has been portrayed for at least the last 10 to 15 years in comics and on film. The oval just started to reappear in things like Dark Knight comics and Batman Earth One.
The reason why some fans come down on Batman 89 so hard since the Nolan films have been released is 2 fold: the Nolan films are newer and fans of the actual books don't read the 70's and 80's source material that the 89 film was based upon to understand how much more pure the 89 film is compared to the modern crime-drama trilogy that Nolan created.
