@Dave_Tacitus I currently have G13 but was eyeing Orbweaver. My main gripe with G13 is the lack of 123456 keys above the wsad.
Main concern re: Orbweaver is the quality of joystick - is it good / bad ok? I don't really need the analog aspect of it, just to reliably do lef/right/up/down (which G13 also sometimes fails at) - for things like "lean" (Q/E) etc.
I've used all of these apart from the Tartarus and my favourite is definitely the Orbweaver - More keys than the Nostromo and comfier than the G13. The software is fine but not as good as Logitech's though.
