I too have fallen out of love with 3E (happened before I even owned the 5E books, though they were out), I said a variation of the above about 2E when 3E came out (the latter is better in every single way) because in that moment it was what I wanted and needed from a D&D game. And yet, if I were to go back to play an older edition today, it would be 2E, not 3E. Thus, personally, I never say never anymore because I know my view can change.
If it were up to me, 3E would still be going strong in this thread and 3.5 would be on its way out along with 4E - just based on my feelings then and how it shapes my feelings now.
