Only been through Charlotte once (rerouted connection), and basically entered in one gate, walked two gates over, and waited for the next flight. Seemed fine based on that (very) limited experience.
LaGuardia seemed better to me last time I was there (August), but it was my destination and I didn't have to go between terminals or wait out a layover. Had to do that there about a decade ago, and it was a hellhole then.
I haven't been there in decades but one of the late night talk hosts that used to regularly make fun of LaGuardia did say after a joke about it that it was actually pretty nice now that the renovations were completed.
