I was just at CSR (Sept 26th-Oct 4th) for a solo trip and loved it. I have also stayed at POFQ several times solo and at CBR once solo, and PORS with family. Saying all that, I have also stayed at AS Sports, AS Music, and POP. I definitely think the moderates are worth it. The rooms are a little bigger, you get the coffee pot and refridgerators, the cover bus stops with benches, more lush landscaping (less concrete), ceiling fans, hot tubs, pool slides, nicer pools, TS restaurants (except POFQ). The moderates are more spread out, so feel less crowded than the values. POFQ is the smallest of any WDW resort so no room is very far from the main building or bus stop. The two PO resorts also have the boat to DTD which I love. However, POFQ and PORS could both do with a refurbishment. CSR has just been refurbished and now has queen size beds. It also has the biggest hot tub on property and a very nice main pool. It is the only moderate to have a health club/spa. For some reason CSR bus stops seem to be one of the closest to the park gates, which is good for tired tootsies at night. (At MK and DS it is the first bus stop, at Epcot it is the second, and at AK it is in the middle.)
The one thing I hate about the values is that it seems like they are always the last bus stop coming out of the parks.
I think I'll subscribe to this thread. I am in the same boat for my May trip. I was at POFQ the last two Mays, at CSR in Sept-Oct, will be at CSR again in Dec, and already have the bounceback offer booked for next Sept/Oct at CBR. Financially I know a Value makes sense for my May trip, but I really want the boat to DTD and/or the remodeled rooms and closer bus stops at CSR. However, I have not stayed at a Value in a couple of years and also want to give them another try.

If I hadn't just stayed at CSR and was not going back to CSR in Dec, I'd definitely pick CSR again. However, I think I want to try something different for my May trip.
