I've had a quad of Chinese Hellatone 8ohm, Mesa 8ohm, & uk 16ohm (same voicing as the chinese) V30's all in the same vintage marshall style cab. They were all broken in. I found the difference pretty noticeable.
Comparing the Mesa to the 8ohm Chinese I found it to sound like many describe - the Mesa sounds like the mids are shifted a little lower. The 16ohm quad had an overall more jagged tone with the sharpest upper mid peak. I also felt like their tone didn't jive as much with how this cab resonates if that makes sense. I need to try get around to trying the Marshall version.
So yeah, I find them different and depending on your cab and amp you'll likely prefer one over the other.
