We had PRUSH and I think I totally prefer it on all counts.
After parties when you rank, generally there are only a few (3-4) that you are dying to go back to, so they get put at the top. A house that is, say, 7th or 8th out of your 12 choices isn't as big a deal to you. Generally PNM's aren't struggling with the choice between the 7th and 8th ranking knowing that they only get invited back to 7 the next day. Meaning, they aren't there fretting over "What if I get my other top choices and tomorrow I want #8 instead of #7?" (Did that make a lick of sense?! It did in my head!

) So you come back the next day and there are your houses. Done.
My biggest problem with SORUSH is that it paves the way for "tent talk", preconceived notions and hurt PNMs. Say ABC is not that strong a house numbers wise or in terms of "coolness", but full of wonderful girls and a great sisterhood. Also, XYZ the reigning top chapter doesn't cut for anything after round 1 but grades. So, Patty PNM goes through Round 1, thinks the ABC girls are great and the XYZ's fine, but not her type. She goes home for the night and has dinner with some of her friends who are also rushing. They all talk about how "cool" XYZ is and how they hated being doubled rushed at ABC and their house is so small!!! The next morning Patty gets her invites and has been invited back to both ABC and XYZ. She really liked ABC, but her friends were saying all that stuff about them last night, and well, XYZ is the best and they asked me back - and she goes to XYZ declining ABC. At the end of that night she thinks XYZ is awesome (they are great rushers after all!) and the next day finds out she was not invited back because she wasn't a 500th generation leagcy with a 4.0, beauty queen title and 5 years of community service. She thinks she's a loser and drops out and ABC lost out on a great NM.
Now, I know this is an extremely exaggerated story, but I think you get my drift. I think letting girls pick lends to picking for superficial reasons. Also, I don't see how seeing who invited you back first makes you realize more where you fit in? So XYZ, the "cool" house didn't invite me back. Well, in PRUSH, even if I DID put them first, if they didn't invite me back they wouldn't be on my next round party list and that would pretty much clue me in that it's not the place for me...

Right?
