I keep trying to 'retire' my former LE-issued 1994 G19.2, but it's proving difficult because it just works so damnably well. It's still the daily carry gun about 75% of the time, depending.
I'm very interested in what you discover comparing the G2 and G5 G17's. I've been on the fence about a G19.5 or G19X for awhile, this might push that over the edge
