I like Crystal PAradise too and stay there often. Mostly to hear Jeronie laugh (you'll see what I mean if you stay there) but also he is a great birder/naturalist. Also Mama (as all her guests end up callling her) is a wonderful cook. However, I think their rates for non-thatched is 75.00 (not incl. tax) and includes a hearty breakfast and dinner.
Clarissa Fall is my next favorite and closer to the Mopan River but is a working farm so not as "jungly" as CPR.
As LF mentioned, Five Sisters is a located above some fantastic waterfalls but is in a pine forest. CPR is on the road to the pine forest and I normally go to CPR and stop by Five Sisters for lunch on a day trip to the falls, caves, and trails. I have stayed at Five Sisters a couple of times but not for more than one night.
Won't comment on the other three as I haven't stayed there but I am familiar with them from friends comments and have also visited two of the other three you mentioned.
Oh, and the Aguada is a good value but it is right in Santa Elena town.
