OG RE4 is one of my all time favorites, but to be honest, I always opt to play the Remake version. There is some shit the OG does better. The atmosphere is better in some sections, the death scenes are gnarlier, and Saddler/Salazar are better. But as an overall package, I just think the Remake does more things better, and I have more fun with it. I don't think that's a knock on the Original. I think an compentent team SHOULD be able to make a superior game to the original if there's 20 years of tech advancement between them.

Also the older I get, the more I realize OG Leon was early mid 2000s cool, but is a cringe fucking dork these days and is only enjoyable if you look at him as a goofball, which I think how most people view him these days anyway. Remake Leon is at least pretty consistent with how he was in RE2R.
