If you use a global offset (at least in my experience), the assist tick will be wrong (in regards to where it should be to be in sync while playing) by whatever your global offset is. For me, my global offset is -.04, so if I sync a song with assist tick it's .04 (early), and once I add -.04 it's in sync for playing. You want to use the sync for playing as your final version that you send in, because that should work for everyone else. But then, of course, you get all the difficulties with the incompatible versions of SM and all that jazz.

Moral of the story is don't judge based on offset unless the whole thing's wrong
