+1 what Mike said.
I'd add that in my opinion (which is admittedly biased) if you feel your quilt is at all a compromise in functionality or comfort compared to whatever traditional bag you were previously using, then you don't have the correct quilt for your size and sleep style. The exception to this is the case where you find comfort in the cocooning of a bag, for whatever psychological reasons, which is pretty difficult to duplicate in a quilt.
I personally consider the primary advantages of a quilt over a bag to be comfort first, versatility second, and lastly, the weight savings is just a big bonus.
The massive variability of user preferences, sizes, sleep quirks, etc, are why I think it's very difficult to translate the "classic" quilt profiles in to an off-the-shelf product, that doesn't end up making quilts look full of compromises. Bear in mind at their core, the vast majority of offerings are very simple in design, which is in stark comparison to the highly shaped designs of the much bigger "sleeping bag" market. There are however, exceptions to this rule, and with new manufacturers/makers entering the market daily, this is rapidly changing due to the simple economics of it.
Still, just like buying a mattress, you should really shouldn't compromise, remember, it's a third of your life, and a much more important third when you're out on the trail beating yourself up.
