I don't like Märzen beers, as a rule. They can't make up their minds.
I love me some Hefeweizen, but I'd avoid Tucher if anything better is available. I like IPA up to about 7.5 abv. Belgian ale and barley wine is gross to me. If I want something stronger, I'd rather just have something stronger.
Light domestic lager can be refreshing. A lot of it is pretty nasty, though. PBR and Old Style are both gross. I thought Miller Beer (red label, available only for about a year in the mid 90s) was great while RedDog (same time frame, same brewery) was disgusting.
I just had some Cass ("the #1 beer in Korea") and thought it was fine. 4.5 abv and not very hoppy.
Breckenridge makes a Vanilla Porter that I like a lot. Porters in general are a good fit for me. I like Guinness, too. It's a light lager, but dark in color.
Boddington's, Old Speckled Hen and similar are excellent in that nitrogen infused vein.
