This. Twice on Sundays (and it's a Sunday right now! So buy two!). At $109 with something like 2-3 days from order to your door, you can't beat it.
The G2S is the SSA, but you have to put a locking spring in place. Once it is in the gun (which takes all of 8 minutes), you can't tell the difference between them. The trigger is incredibly tight, clear, light, crisp, and with a lovely reset. It is night and day.
The SSA-E would be my go to for a recce gun that I intended on taking out beyond 300m with a magnified optic. Even then, a G2S is no slouch. At that point, you're really just looking for spare percentage points of performance.
