I have stayed at all variations of seasonals, permies, full timers,ownership parks etc.
As a transient I prefer to be amongst other transients. CG with seasonals are OK if seasonals are separated and given their own area AWAY from transients.
Places where transients and seasonals are mixed together are the worst, seasonals seem to consider transients as a nuisance to their community when everyone is mixed together.
Places with permanents are generally uninviting. While some are more tidy than others. Permanents always have a collection of their possessions scattered about the site.
As a vacation/weekend camper I prefer transient only campsites. The atmosphere is generally more casual and relaxing vs. places with permies.
Permanent places do not allow you to escape the rat race and the real world because many staying there are actively participating in the rat race.
It's harder to forget the rat race when it is in your face.
Nevertheless if I'm hoteling it in the RV. I will pick a CG that is convenient to my ultimate destination. In those cases I may be in town for a wedding, or a family function, holiday, birthday or whatever. I'm not camping in the traditional sense but am in town to attend some sort of event.
I will stay at any relatively safe CG that will have me. When hoteling it I am generally gone during the day and only using the RV as a hotel room.
I try to use the RV as much as possible and prefer the RV over a hotel.
When hoteling most any CG will do. The mix of transients, seasonals and permanents is less of a factor.
However when vacation camping I only stay at places that prefer and cater to transients campers
