The reason why SSJ3 isn't being used as much is because its the most draining form out of all of them. Not only does it require a whole bunch of energy to activate SSJ3, it also drains a lot in that form. SSJ1 and SSJ2 are forms he got used to and probably mastered (Like when Goku stayed SSJ1 before the Cell game so he can get used to it). I believe SSG and SSB may have a higher activation cost than SSJ3, however, you have control on your ki during the forms. That's why Vegeta says SSJ3 is useless since they'll lose all their ki before the fight even starts.
