It depends on what you're looking for. I am a Marshall guy, and Channel 2 of the Paul (with gain between 10 o'clock and noon, with presence and mids turned up) is way more old school Marshall than I ever got out of other Diezel amps (Einstein or VH4). Never owned the Schmidt. The Paul is very touch responsive and dynamic as well, with great clarity and note separation. Lots of great features on this amp, not the least of which is a really great clean channel that offers plenty of chime and jangle with strats and teles.
If you're looking to do more of a modern metal thing, I would probably look to other Diezel amps rather than the Paul. Once you push the gain to 1 'o clock or more on channel 2 of the Paul, the amp really softens up and loses that zing/bite and clarity that I always need to have. I think you can hear this on some of the clips that have been posted online. The key for me with the Paul is to keep gain on Channel 2 below noon and use channel 3 when I want more drive and compression.
