I rushed School of Rock and got a front row seat that thankfully wasn't partial view since it was enough to the center, but I saw others who rushed who were placed in the far side and I could tell that they had some views blocked, they kept trying to crane to the right to see what was going on. Also being up front really hurt my senses from being so close to the lights and noise, my eyes kept watering from it. Still, I loved the show, and it was still worth it for the low price! If you're only concerned with getting your ticket as cheap as possible do rush, but if those factors would bother you I'd say go for TKTS, it'll probably be more expensive but you won't have to worry about partial view or about being too close to all the lights and noise.
Also I second the statements towards PThespian. I truly admire everything I"ve seen you say and how gung-ho you are about this show. Many of your posts were the reason I put this show on my list of shows to see while I was on Broadway. Thank you and keep doing what you've been doing.
