I'm not far away from you either, in New Hudson. We don't have much direct experience since the pool is exactly 1 year old, but we do have a main drain.
I also looked into this when we bought our pool last year. Trying to be as objective as possible here, I think the benefits of the main drain include: a) better water circulation, leading to better filtration and even water temperature; b) can run the filter at lower water levels, if needed (startup, during drain-down, maintenance); c) less vacuuming. The drawbacks are a) another worrybead for leaks; b) winterizing has the additional step of taking care of the main drain; c) additional cost, albeit small.
With all that said, my experience in the decision-making process was based on my brother's pool, who has a main drain (AG) working for about 6 years. He loves it. And now that I have a pool with main drain, I don't think I'd would have second thoughts about doing another - we really like it, and have turned it off periodically and notice a lot more debris on the pool floor. A key for me in making myself comfortable in the decision was talking with my installer, who had tons of local experience installing AG pools with main drains. And in watching him and his crew setup my pool, I knew the work quality of the entire installation was better than I had hoped. I truly believe that my liner is more likely to leak due to random swimmer usage than my main drain is likely to leak. If you have confidence in the installers putting up your pool, then there is no reason to worry about a main drain leaking.
And now that I've winterized this drain once, I'm not worried about that step as it truly takes only 5 minutes to pour 4-5 jugs of RV anti-freeze into the lines once I've disconnected the skimmer. Open the main drain valve in the spring until all signs of pink fluid are gone and it's done!
Good luck with your new pool!
