Manitou Swinger 3-way Air went on my Quasi about two months ago.
Was using Vanilla RC.
Can't tell if the bike is any less plush at this time, maybe do a back-2-back ride with shock swap in the middle sometime to check maybe not as I'd rather ride than do work on the bike.
Got back last weekend, for spending a week in Moab.
So now that I've enough miles on it to form an opinion, I'd say that the opinion is "it just works dang well." Most happy with the Swinger. Kinda surprising that, never had a huge opinion of Manitou stuff until now.
fwiw: me == 230#, camelbak ~10, bike setup in 6" travel and for the air shock. Main chamber at 160 ~ 170 psi, SPV chamber at 80 psi. Bike climbs like a goat and downhills awesomely well. Only downhill in Moab that I did that felt "a little rough" was the Top of The World trail, the first 4.x miles was steep, fast, tasty, and I could have used bigger tires.
