Do you pin your seam before sewing, or let your seams "nest" together? You may need to do this as the pieces might be shifting as you sew them.
I'm a perfectionist so I would rip and fix mine... but I see loads of people that are happy with their imperfections. It's just whatever works for you. The fact that you posted to ask other people's opinions tells me that you are bothered by your seams not matching up. I'd pick them out and try again. A lot of sewing (not just quilts) involves picking and re-trying. Nothing wrong with that!
