I went with a SIG P365 (eventually two of them) when deciding on a small CCW pistol. I was considering the Shield Plus and G43X most strongly as competition against it, and the Hellcat a bit further distant. I like and trust SIG (I have a P229, I used to have another P229 and a P226, and at the time I still had an old P290RS and P250 Compact), though I also like and trust S&W and I don't have anything against the others. The SIG felt right in my hand, and after I bought it, it is so comfortable to shoot and so accurate for me that I know I made the right choice.
After about 6 months of near daily carrying I wanted to add a second carry gun (I live in MD, I couldn't get a local CCW permit until Bruen, I am a teacher so I can't carry to work so I don't carry on days I don't leave the house after I get home from work). I don't carry a dirty gun, I like to have several range sessions before I clean a gun, and I don't want to go too long without shooting my carry gun. So, I was going to buy a 2nd carry gun, one to shoot for a couple months while I carried the other. At first, I thought I'd go with the G43x (it had been a close 2nd when I bought my P365), but in the end I bought a 2nd P365. I am a fan of variety, even in carry guns I'm OK with somewhat of a rotation as long as they have a similar MOA, and I went with a duplicate, so that should say something about how highly I think of my P365.
One problem that isn't uncommon with the P365, the front night sight can go dim, happened with my spare P365. Other than that, I have had no issues with 2-3K rounds through each gun. I haven't yet sent it to SIG to fix it, but I doubt I'll have any trouble when I do.
