Personally, I like the Belton location a lot. I think the DFW bash location has an advantage though because of the obvious airport advantages and Interstate connections.
Post Coronavirus lockdown, I think Belton has an advantage for people that want to go to Lockhart and Austin for even more BBQ pre or post Bash. Personally, in addition to the Bash, Slovachek's in West is a big draw for me. Of course, I need to visit Lockhart as well. Someday I'll venture a little farther to Snow's and some of the BBQ joints in Austin.
At this point, work permitting, I'm good with anything from El Paso to Texarkana, and Amarillo to Port Aransas!
