I'm willing to bet I've used more variety of brands of tires than most people out there. Dunlop, Bridgestone, Artrax, Maxxis, Kenda, Pirelli, Sedona, IRC, Michelin, and most recently the new TUSK tires.
My favorite all time tire ever is the Bridgestone M403/404 combo. We used these tires everywhere, and I mean everywhere. I still have a few new ones and slide them up on my 90's bikes (they aren't the fat size for my 450).
90% of the people out there now seem to just get hung on whatever the "cool" Dunlop at the time is, which right now is the MX33. If you actually review the specs, for Ohio/PA you really should be running the MX53. But from talking to Dunlop folks they tell me the 33 has a much wider range while the 53 is more suited to hard only. I've used both, no complaints.
I've run a ton of the new model Bridgestone X30 and X20. They are fine, I don't really have any complaints. I lean toward the X20 but that's mainly because I don't actually ride a ton in Ohio anymore compared to before.
I have a set of X40 on the rack right now, which are considered the more hard terrain, but I've read some good reviews on them stating they work well in a variety. Actually I might have a set of each on the rack, X20, X30, X40.
So I recently was intrigued by the Tusk tires and have a set on my 450 now. I have the "EMEX T35" which you pronounce MX haha. So far they have worked good and held up good too! Again going on specs for Ohio/PA we probably want the T45 rear, however the T35 has worked pretty nicely all around in a lot of different conditions so far.
