I find the G checkpoint is rarely packed when I'm there (1200 or 1800 usually), whereas I've had some pretty long lines in T3.
It can also be quite a long walk if the checkpoint at gate 75 is closed (which is not uncommon).
Actually thinking about it now, are you sure there are still three checkpoints in T3? They reorganized things a while back, and I'm having a hard time picturing a third checkpoint. There's one at 75 (right beside the connector to G) and one around 70, but I don't think there's a third.
