Groomsmen’s tux rentals

I need opinions on where my fiancé and his 7 groomsmen should rent their suits. Generation tux vs The Black Tux vs Mens Warehouse vs Joseph A Bank vs any other suggestions! We live in upstate NY and he has groomsmen all across NYS, NYC, and Texas. We were leaning Generation then but then heard mixed reviews.

Also should my fiancé buy his tux to make sure it’ll fit right/be able to alter and have far in advance? Or do most grooms rent as well? I’m only stressing bc I’m type A and I need nothing to go wrong right before this wedding to avoid a meltdown.
