I'm on the 350, but have zero insight on the Latitude. I was an FO for 12 years on the XL and it was time to move. I could have had the Falcon, the Latitude, or the 350. The Falcons are getting old, I'd had all of Cessna I could stand, so that left the 350.
I love the plane...it is a great performer (engine out procedure out of ASE is "fly runway heading") and the passengers love it. Long duty days just like the XL. Fewer legs, but longer legs. Road QOL not much better than the XL, but a little better. More bigger airports and my passport seems to be used more often. The automation is awesome. It has Mach hold, but not autothrottles, or auto-brakes. Generally lands well, but crosswind landings are different because it can't take much wing-down.
For me the biggest negative is the bigger cabin to keep clean and stocked. A big positive are the creature comforts.
