All I've tried are Enlightened Equipment quilts. I run regular length and wide. I'm Joe average, 5'10" 190. I've had four and still have two of them, just sold the others to dial in my gear. Generally speaking I'm a terrible sleeper so I will do about whatever it takes for a good nights sleep. I've had folks say they are bad in cold but I had no issues down to single digits. I knew it was going to be cold so wore my standard skull cap and also a fleece hood that goes down around the shoulders. I didn't feel like it was a minus to my gear as it was also worn during the day due to the bitter cold. I now have a synthetic quilt, 30 degree, that will unzip to lay completely flat. Also have a 10 degree down with sewn footbox. Both quilts together cost about what one WM bag will run you. Any specific questions?
