Played D&D 5e for years, dabbled in PF 2e, but GURPS is my home now. In the same way Pathfinder increases the richness of mechanics over D&D, GURPS goes even further.
I like playing characters that can solve problems in creative ways. My last two D&D characters were an Artificer and an Order of Scribes Wizard. D&D is pretty frustrating for this though, which is part of what pushed me to a system with more customization.
My current character is Umak Tchuali, a wizard specialized in meta-magic. He can block spells, deflect them, reflect them, change how they work, etc. Kinda like a D&D Order of Scribes wizard mixed with a sorcerer .
