I'm impatient. I don't want to sit there waiting for a prompt to come back when I could have had a good enough answer thirty seconds ago. I'm not doing split-the-atom things on an average day. Most of what I'm automating is pretty straightforward. When I actually need to do something strategic (like architectural review) I'll fire up Fable, as there's a nontrivial difference. For everything else, Grok or Kimi K3 is close enough and considerably faster.
