> I grew up using Hammer and this simply blows it out of the water.
Strange to read "I grew up using Hammer." when I still see Hammer as a newfangled update to Worldcraft.
No Quake map editor will let you do anything the Quake engine can't, of course.
If you draw your maps on paper first, as id Software did[0], then the editor you use doesn't matter so much.
J.A.C.K.[1] is the current torchbearer for the Hammer lineage.
Also there is a community fork of Trenchbroom[2] that exists because Trenchbroom includes slop. Or "machine generated code" or "wAIfu generated code" or however salves your feelings.
"The map editor everybody uses" is reductionist.
