Any preference on your carry choice of the two?
I'm not WarEagle700 and won't pretend to speak for him, but having moved from a G19 myself to a X-Compact and a P365, I'll give my opinion.
I carried the G19 for years, and it's a great gun and I still have mine. But, after shooting a P320 X-Five for a couple of years now in the Carry Optics division of USPSA, I liked it so much that I bought a X-Compact and put a red dot on it. I love the gun and shoot it very well. It is about the same size as my G19, but easier for me to shoot well (and faster).
That said, about a week after I bought the X-Compact, I got a great deal on a new P365 that I couldn't pass up. I ended up putting a Grey Guns straight trigger on it just so that it had the same feel to me as the X-Compact and my X-Five. I put a Crimson Trace green laser on it and I carry it with a 12rd mag and a spare 15rd mag. Obviously it is smaller and lighter and (to me) easier to carry, especially in warm weather. The green laser helps tremendously with longer range shots and I still have 28 rds on board.
So, I find myself carrying the P365 the majority (90%) of the time now days. Sometimes in my front pocket (if wearing cargo shorts), or in a Vedder LightTuck with jeans.
