For time building, would y’all suggest purchasing a 150/152 or renting for $100 a hour wet?

I’m in college full time and a part time CFI. I want to pursue airlines, and I understand that seniority is everything, so ideally I’d like to have 1500 hours upon graduation. There is little demand for instruction in my area, so this rental / Aircraft purchase would be an additional source to gain hours while in college.

Thanks.
