I have lived in base with a 30min drive. I have transcon commuted. It is only part of the decision.

I went to the place I felt I would have the best career and long term security. Den has TK at UA, huge good deal if you want to do that. Outside of that consideration, I am happier be a DL commuter from another airlines pilot base.

Commuting is the devil to some. Not to all. I like options.
