Researching pool for Michigan

Researching new pool in SE Michigan - Had small Intex "test pool" the last three years, now looking at 24 or 28' x 54" doughboy or similar manufacturer. Any recommendations on other manufactures who build quality pools? Thoughts on filter and pump sizes for 24 or 28' x 54"? I was leaning towards a sand filter setup, and a one or two speed pump. Most retailers in Michigan seem to sell Doughboy filter & pumps with Doughboy pools. Any concerns with the quality of their equipment vs. Pentair or non-OEM setup? Thank you for any recommendations you could share!
