GURPS people always recommend it but never explain why. What's actually good about it compared to something like Pathfinder 2e? It seems to me it would be really hard to find players. With Pathfinder I can at least tell my players it shares a legacy with D&D so they were receptive to switching systems.
Is there anything GURPS does particularly well over other systems? I know hardly anything about it. With PF2e there are a few easy-to-rattle-off features that drew me to it like the three action economy and better tools for game balancing as a GM.
