I wonder if Chevrolet type forums get discussions like this comparing Chevy to Ford?
Long story short the situation is "iffy" at the moment... many coders went to Xen but because their site welcomes them, has an area for paid mods and such. Was this because it lacked so many vBulletin features as Katie put it ever so lightly or was it to help improve the number of add-ons by doing so in-turn helping sell the base product? Heck I don't know and unless Kier or someone else from xen specifically stated so no sense drawing conclusions but we can see that many like that system and that's from the last time I was on the site which was well over a year ago, by now I would surmise things are much better at the xenforo site especially since the lawsuit was dropped/settled.
Does it have the same number of add-ons vBulletin 4 does? No but give it time, how the current setup is seems to work well and is sure to improve. When/If we finally implement something like that here though you'll see many coders return (not an official statement or hint although it has been discussed many times over, possibility mind you = maybe

).
Although to be fair and flat out honest, if you code well and have a good business structure and work ethic then running off to xenforo just because it seems to welcome coders with open arms would have been silly - I've seen many say "I'm no longer coding for vB only Xenforo" and that's just stupid to say and do in my opinion - if you have talent and are in it to make money (why you argued you ran to xen in the first place i.e. paid mod area/selling them there etc) then why not code for both? Some people contradict themselves so much it makes me laugh more than some of you at statements by members here who you should clearly know do not understand coding at all.
Edit: Moved to community lounge, seemed out of place being in just vB5 general discussions
