Flipping the wheel requires repeatability in the positioning of the wheel in the stand. On stands with Vee notches for the axles, that may not happen so well. Gauges are cheap, work really well and checking dish is something you only need to do two or three times in a build so it really isn't a big deal. (I did modify my really cheap gauge so I no longer have to take off the QR or nut.)

I build wheels about once a year. Over 40+ years, that's a few. But having a cheap, light, easy to store and move stand that take no workbench space works for me just fine. When I do have a wheel or two to build, I do it on the dining room table. Good light, good music, comfortable chair. Check the dish a couple of steps away on the kitchen floor.

When I've got a wheel with an issue, that same stands gets put on my workbench and put away after. I use the fancy truing stands at the shop I volunteer at. Nice. But I am happy to leave those boat anchors at the shop and use my light and portable one at home.
