Seems like it would be difficult to consistently get all 3 players a full 48 min at PG or SG. Getting 5 players 48 min. is a whole lot easier.
Anyway if you're just asking this as a hypothetical question -- in general, assuming all players are the same age/height, you'll get more total pops with 2 position training. While 1 position training is obviously faster, it's not double the speed. That said, I'm not recommending either. & 3 vs. 5 makes the difference less of an issue than 3 vs. 6 players.
Honestly it all depends on your situation / what you're trying to achieve. If you truly had 5-6 players worthy of training, you could build up a deep team cheaply with 2 position training. Guessing that most people will advise you to do 1 position training though. (If your goal is training a "franchise player" as quickly as possible, definitely go with 1 position training)
