Work life balance

I currently hold a patient facing role in therapy. I've had some good interviews with a company selling joint replacement components.. I currently work 4 tens with 3 day weekends. I'm off at 5:15-540 every day but do go in as early as patients show up. So realistically 4 11/12 hour shifts.

Now how would joint replacement sales associate/rep compare work life balance ? I'm in a mid size city of around 400k people and the territory is mostly local so assuming I'm not leaving town and staying in a hotel.
