I've always had good experiences with standing. I've done it at the O'Neill, Booth, Lunt-Fontanne, Cort, Belasco, Circle in the Square, Nederlander and Winter Garden.
I mean, it's always a bit of a pain to have to stand for the whole show. My feet and knees always get kinda tired, but it's not too bad. I'm 5'10'', so I've never had any problem with the height of the bar/wall. I've always been able to lean comfortably on them.
I've also always found the view to be good. Though, I would prefer to be closer to the stage, the rear-orchestra doesn't feel as far away as sitting in, say, the rear-mezz or balcony, and I've always been able to see everything of importance.
Another advantage to SRO is that you can do some things with greater ease. You get a bit more breathing room, so you can fidget without bothering anyone, stretch, get something out of your bag, take a drink of water, etc. Plus you can pop over to the bathroom as soon as the lights go up at intermission, and beat the lines. And if you like to stage-door, it's easy to beat the crowds and nab a good spot.
