I "grew up" shooting 1911s, and they're still my favorite pistol of all time. I currently carry a P365XL as a primary, with MS. I would not trade it for any compact 1911, as it just makes so much more sense from a maintenance, capacity and "value" perspective. Having said that, a P365 trigger of any sort is NOT anywhere near comparable to a 1911, and you will notice it right away. The current iteration of the P365 MS is skimpy, and not crisp/positive like a good 1911 safety. It's not bad, it's just not the same.
For ME, the advantage in weight, capacity, cost, etc make the juice worth the squeeze. Might be different for you - I'd strongly recommend shooting a rental or loaner XL against your M&P Compact to see what the real world differences are.
