There is so much more that should go into this type of decision outside of the details you've laid out. Like rebuilder alluded to, where do you want to live and why? Non-compete clause? In addition to that, is your tail covered? (Better be.) What is the rate of partnership in Dallas? How many patients per hour are you seeing? Are you working 130 or 150 hours in Dallas? Big difference IMO. Nights, weekends, holidays split evenly or placed on the non-partners primarily? Admin responsibilities at each place? What's the group like at each place? Retention? And you mention hourly rates, but how are these calculated? In my experience in Texas there is usually a productivity based component. You need to know the ins and outs of where that "approximately $x/hr" comes from. Wary of the place who says "We have guys making 400+K first year as a non-partner", not knowing that figure is from the fastest, highest earning doc they've ever had, and then find yourself working 160+ hours a month including tons of nights, weekends, and holidays for $180 an hour. Finally any BS garbage in the contract? (Have an attorney who specializes in physician contracts evaluate it. I did. Well worth the $1K).
As for full disclosure I am an employee in Dallas, but did evaluate multiple jobs including IC jobs in Texas and elsewhere. Really the only way to make this decision is to sit down and 1. Figure out what pieces of information are important (i.e.: the stuff I laid out above was important to me), 2. Weigh them carefully between each job, 3. Have an attorney make sure the contract says what you think it says (I promise you aren't smart enough to do this... even though you think you are!), and 3. spend some time making the decision.
Overall Texas is a nice place to practice. Good luck.
