Out of those, HT-5. What's your budget, where do you live, will you buy used, and what are your musical influences? (band examples are helpful)
#3
I play blues and classic rock mostly. Yeah I would buy used but there ain't nobody selling where I live, its Cumbria England btw. Influences from zz top, van halen, jimi Hendrix and G n R
#4
Definitely the Blackstar. It'll be better sounding, no matter what your music style.

Especially if you play bands like what you listed, and don't need distortion for Nile.
