Houston and Austin

I am contemplating a move to either Houston or Austin. I am leaning towards Houston because I have family there. I haven't been back since I was a kid, but I have job offers in both cities (the miracles of Zoom is having job offers without ever setting foot in the city)

I have about a week in Feb to check out both cities. Should I fly to Houston and spend a few days then fly or drive to Austin. If I rent a car, I think i'll need to drive back to wherever I rented it to return it.
