Many prefer the P239 for CCW in bigger than .380. Personally I can't speak to that as I use my P228. What ever fits and feels best in your hands and will suit your needs best is what you should choose over brand name (specifically or hype generated). SiG's work for me and so they 're what I own. I don't know anything about your hands nor what fits them best. You do, or they will help you decide.
I've fired a friends LCP. I didn't like it one bit. It was absolutely too small for my hands and I felt as if it were going to flip out of my grip every time it went off. However, for him when he rides his bike, it's the perfect option to his normal XD9SC.
Just like glasses frames or underwear, the choice is purely personal. For those whom I've read (here and on other forums) it's as great as sliced bread.
