Do not talk about such thing when I am not around! (Will probably- HOPEFULLY- get back my newly repaired computer within two weeks.)
I kinda like the syle more in Left 4 dead 1. But overall the sequal is better, it's so much improvements in it that feels odd going back to the first game. Like the maps has more varriations, and challanges that is more than just "stay here and defend for a while".
But also one of the major flaws in L4D1 is that annyoing "everyone get into that small room and defend" tactic that just made the game a lot more eaiser. It made a lot of parts that was supposed to be very hard pretty effortless to get throw.
I think I like the L4D2 more cause it's harder and really requires a good team to get far in on expert, and not some pyromaniac.
