i have owned three summits and they are great stands, now i use nothing but ole man, as stated above they are very quiet and they are the most comfortable climber i've ever used, in all fairness i have never tried a tree lounge and have not used any of the new summits, they look very nice and i don't think you'd be unhappy with either choice.

i'm with pa trophy on the ole man stuff though, i've done some of my best sleeping in mine
