Retina MBP vs 27" iMac regret, anyone?

I recently purchased a 13" MBP (mid-spec late 2013) however I feel that the larger screen, better spec'ed iMac 27" would be better for me. However I've fell in love with the retina display, I have an iPhone 5S, iPad Air, and I use those retina display devices daily. Has anyone gotten an iMac recently and felt they regretted it and would have been much happier with the smaller, but higher resolution display of the retina MBP?
