These are utilitarian speakers, at the end of the day. High wattage to handle basically any head, and the highs and lows, though extreme, can be leveraged to meet a variety of needs and play many different styles. They're not nice to listen to by any means, but to some extent electric guitar doesn't need to be nice to listen to. It's a harsh instrument to some extent, and if you're someone who leans into that part of the sound of a guitar, I can see loving these speakers, and I totally get why they've got a certain cult following despite also being maligned.
Billie Joe from Green Day is a great example of someone who leverages the strengths of the T-75 to achieve a specific goal, which seems to be providing a foundation for his guitar tone, lots of lows and highs, and then fills it in with a Greenback or V30. (which I believe is the method he used on American Idiot and 21CB)
Me personally, I'm probably going to sell my T-75 cab, partially because I own 3 4x12s for my JCM2000 DSL, and a DSL 40CR, and can't justify having this much gear. But also, I do like guitar to sound a little "nice" as well as harsh. I recently fell in love with the Celestion V-Type, which has plenty of utility, but also just has a pleasant mid range as well. I'll also be holding on to an EVH 4X12 with Greenbacks, again, for that nice mid range.
