I too have stayed at the RP. It has been awhile, but we liked it very much. The main driver was that it was the cheapest of the Uni resorts, but we thought it was very nice. Dollar value wise, I think you are getting more for your money with the Uni resort hotels over the WDW hotels.
I guess for me, comparing Uni and WDW hotels is apples and oranges. You are not just comparing 10 hotels in Orlando to see which is best, fits your budget, location, etc. But you are comparing apples and oranges. For WDW, you want to stay in the "bubble". You are paying for the WDW experience...which Disney knows and for which is charging an arm and a leg. For me, the main reason to stay at a Uni hotel is the Express Pass. Otherwise, we would stay elsewhere for less money.
But just comparing room quality, I would agree with those who state the Uni rooms are as nice as, and more so, most WDW Deluxe rooms.
I do think this is a good place to come and get advice. You are going to find bias everywhere. But I also look everywhere to find opinions and reviews. Every site or review aggregator is imperfect, so the more places you go to look, the better chance you have to suss out the best and most reliable information about a place.
