When it comes to TV properties...
I've only ever read The Dell/Gold Key Star Treks (Love those covers),and whomever printed the old Space 1999 series. Otherwise I haven't and don't support the current stuff.
Not even Star Wars.
If we're talking about Pulp characters and such I read and collect Conan,Kull, Kane,Tarzan, The Shadow,Green Hornet and The Lone Ranger.
Like Silveragemarvelman I'd like either a collection on The Hanna Barbera TV Superheroes as well as Thundarr The Barbarian.
