the reason why i dont play MTA is there is too many cheaters and almost no admins online
you should recheck
mta has build in anticheat and detects and kicks sobeit or any other modification on join.
unless you are pro hacker with custom not released cheats you cant cheat.
and ban is based on serials, so there is no evading(serials don't change even with reinstall of windows)
and in case by cheating you think too much power given to players, well, that's server, not game problem.

as a MTA scripter i say that maybe not easily, but we could set up adrenalinex in mta in a relatively short time and develop it WAY beyond possibilities of sa-mp,
but i understand that most likeley it wont happen just because of reasons firefox said...
and about the "sa-mp has more players" thing:
while it is absolutely true i can warrant you that with as orginal server as ax is we would get WAY more pepole in mta then in sa-mp.
also, other lame reasons like "i dont like the chatbox/downloading/etc" are resolvable
downloading: already there are some file streamers that silently sends the files to your client while you race, eliminating the download at beginning of map.
chatbox: just re-create it completely, very possible.
