It's a personal thing. I avoid loupes because--to me--they have a restricted field of view and too much edge distortion, unless the viewing angle is perfectly vertical. I use a folding ~5x linen tester for general proposes (Google search 'linen testers'), and a ~10x old school microscope eye piece tube (lens at each end, viewed in an inverted fashion). I have a 40x old school drafting microscope for closer-in viewing--rarely use it. To me it's pointless viewing coins under ultra high magnification--every coin viewed would have 'flaws'.
