Do the math. You need about 2 to 3k tpic to be pretty competitive. Usually you're supposed to spend about 2 or 3 years as an FO to become captain. So a few years as an FO and two or three years as captain, about 5 to 6 years to mainline. That's best case scenario, it could be 10 years or more depending on how you pursue it. Usually low quality of life means you upgrade quicker, better qol by choosing a certain base or type of plane could delay your upgrade. I would not sacrifice having a life in order to get that quick upgrade but on the other hand I would not delay you becoming competitive because you want a good qol at the regional.
