I have read somewhere that if you have astigmatism, then the Omnigrids are difficult to use. I use only Omnigrids since I started quilting. Have full set all sizes, even doubles that were gifted to me. I love them for their accuracy and many uses.
I actually have purchased some Creative grids in very special sizes (for a class or particular pattern), find the cost and limits of use to be prohibitive
to replace all my OG's.
Each his/her own I guess.
