I mean, different strokes for different folks, but it's really hard for me to comprehend someone not liking a wizard, even though I don't own one. I've played them plenty, and they are incredible. They aren't exactly for my personal musical style, but to deny their greatness seems odd. If I had unlimited funds I would absolutely want one in the stable.
Although, on the same token, I don't "get" mark amps like lots of others do. I've owned half a dozen, and played a 2c+, 2c++, and a 2c+coli. And to me, everything except for the Master of Puppets/Petrucci settings sounds like a sloppy, honky mess. I would never say it's a bad amp though, on the contrary - they're iconic, and have a signature sound thats immediately recognizable.
I guess it all comes down to your personal playing style and the music you want to accomplish with whatever the piece of gear is.
If you want to play surgically tight tech-death, than an Orange OR100 isnt the right tool, even though its an amazing amp.
