For me it's what I call the 'weekend test': Do I like tinkering with this thing enough that I'd want to play around with it on a weekend / in my own time, just for fun. This needs to check a lot of boxes: is it easy and quick to setup, do I need some hard to obtain 'license key', does everything work out of box or at least is easy enough to fix, and most importantly: is it a joy to use (which is entirely subjective though). If something doesn't pass this test then I also don't want to waste time with it at work. In a nutshell this is also why wheels should be reinvented over and over again, and if it's just for the sole reason that the new wheel feels better to just the person who reinvented it. Chances are other people will feel the same after trying the new wheel (on a weekend, hah) and start using it (or not and that's fine too), but in the end this is how innovation happens.
