I don't think I've tried a 2-stage Geiselle,
With the exception of the 2 versions of the 3-Gun triggers, all the Geiselle triggers are 2 stage.
I have 3 different Geiselle models, G2S, SSA, & SSA-E; never pulled an RRA.
None of them have any real perceptible creep, to me, but there's a difference in how crisp they break & how they feel.
The G2S is not quite as clean as the SSA & the SSA is not quite a clean as the SSA-E which has a glass rod break & for me, is about dead solid perfect. But even on sale, it's a $168 dollar trigger & only belongs on a precision rifle, IMO.
The weights are 3.8 for the G2S, 3.8 for the SSA, & 3.5 for the SSA-E with an electronic gauge.
The best analogy I can give is to a 1911 trigger......as the top of the sear is slightly rounded from a sharp intersection of the primary angle & the breakaway angle, the break goes from very clean to "softer" though the weight is the same.
It's the same kind of feeling with an SSA-E vs the SSA & G2S.
JME, YMMV.
