Dave,
My very personal opinion is that I would prefer Hamilton. Reason being it has domed crystal, on one side, at least, for the model you've got your eyes on & not that easy to find a Tissot with domed crystal, from what I've seen at boutiques anyway.
Plus Hamilton isn't as common as Tissot
Most importantly, choose the design that you like the most & pleases your eye. Remember that you'll be wearing your watch longer than you'll be sitting in your car, unless you drive for a living.
