Depends. When I got mine, I ended up selling my XTC, however I kept my Herbert. The PT100 is a great amp, and it covers a ton of ground, but IMO its easier to leave the super-ultra-heavy modern rock tones to other amps. This is not to say the PT100 isn't "modern" sounding, it just doesn't easily deliver the kind of tones that are the main point of amps like the Herbert, and others of that similar tonal variety.
Of the amps in your list, I have only owned a Shiva, and I really didn't like it, so its hard to say with that one...the others I have not played but they seem to be in the souped-up Marshall realm which is exactly what the PT100 is.
