I like its funky, modern vibe and the colors, but I can't tell you if it's "worth" quilting because worth is determined by you. Do you want to put any more time, money and thought into it, or are you ready to pass it along as a UFO to someone else, and be free of it?
Could just be that you're in the stage that most everyone reaches in making a quilt--the 'eh, not so much" stage where we waffle between giving up or going on. But then once it's quilted, suddenly we like it again.
I would put a statute of limitations on myself as to how much longer to keep it unfinished. IN other words, make up your mind by Nov 30 (or whatever you determine) and if you haven't wanted to pick it up again, give it away as is. Decision is made and you can move on, one way or another.
