In all seriousness, I like both the old and new games equally, but for entirely different reasons. The old ones had better story/atmosphere, while the new games have much better gameplay (and phenomenal voice acting IMO). With all these in mind, both styles level out to be equally enjoyable games.
I believe the ideal RE game is one that has the best of both worlds: great story, great atmosphere, and fun/functional gameplay. There are very few RE games that I feel fit this criteria, namely: RE4 and RER. I think both of those had the best blend of the new and the old. And not to mention that RER arguably had one of the best stories of all the RE games.
