The steyr precocks to 72% vs the glocks 50%, so the pull is shorter.
There is also no stacking effect (it doesn't get heavier as you pull).
It is also much crisper due to all the parts being in a steel subframe instead of some parts embedded into the polymer fram (polymer flexes under pressure more than steel).
however the glock trigger can be changed out w/ different parts for an easier pull, less overtravel, etc. But out of the box the steyr trigger is way nicer, it also wears in smoother over time too.
