I have experiences with all three. all three are anti-axiety drugs but klonopin does have a muscle relaxant in it. blue xanax and the valium are best, personally i think it has to do with the manufacturing quality of the pill. i feel that the valium has the least amount of sedative effects on the body followed by the xanax and ofcourse the klonopin in last. personally the valiums and xanaxs are the most fun of the three but when drinking with the xanax i find it easy to REALLY lose all sort of anxiety that you would have. the valium is still fun but i feel i'm able to make better decisions even when ripped off of it. klonopins and alcohol = sleepy time.
a funny example with xanax is when i was down in phily for my boys party. This kid had some bud and laced it w/ xanax w/o telling anybody and a couple of us went up to a second story roof/balcony thing to put something in the air. about 2/3's thru the sipher one of the kids started trying to make a cash bet w/ all of us that he could do a backflip off the roof and land on his feet. believe that huh?!?! all of us talked him out of it thanks god, or else he would have been on the internet at stupidvideos.com, lol.
by the way the rest of us in the sipher were tore up from the floor up for a long time. hope that helps, if not i got more info for ya.
