You are correct. The flatter your blocks are the better the quilting will look. Making out of plane blocks with perfect seams is just kicking the can down the road as it will save a headache now but create a new one later.

Almost all of us have occasional seam that don't line up perfectly. It isn't a big deal in the finished quilt and no one but you is likely to notice it. The blocks look beautiful by the way.
