I’m somewhat of a newbie and don’t have much experience with firearms that AREN’T Glocks. That said, I really enjoy the 43X! I actually had a G26 and loved shooting it, but found it a bit uncomfortable to carry. I’m fairly thin so unless I want to start wearing larger clothing, width plays a pretty big role in comfort and conceal-ability. I ended up getting the 43X instead and it’s noticeably more comfortable to carry (which equals me carrying more often!). The G19-length frame makes it incredibly comfortable in-hand.
I realize I’ve written the word comfort far too many times… but you get my point.
