While RE2 is technically (in all respects) the better game, the original is and will always be my favorite; it's the perfect b-movie experience. 3 and Code Veronica are fine. Survivor is unplayable. Haven't played Survivor 2. Survivor 4 is average. Remake is nice, if unnecessary, and Zero introduces needless plot elements that obviously weren't there to begin with and ultimately complicate the overall narrative about as much as 4 and 5 do. Both Outbreaks lack a solid single-player experience. Some would call 4 innovative, but I call it uninspired and, save for some characters, the game really has no business being an RE sequel proper, and 5 is pretty ridiculous. Man, the continuity in this franchise is a mess.
