Ian Carr & Nucleus on CD BGO twofers or Torrid Zone Box set?

Hi, title kind of says it all. I am a huge jazz fusion fan but had never heard Ian Carr/Nucleus until just this week, randomly listening on YouTube.

So as someone who would be making a purchase which has the better sound quality, the twofers on BGO or the box set?

I tried searching but couldn’t find any info on the sound quality of the box set. Thanks in advance for any guidance.

 

I have all the BGO towfers and I think they sound great!

a liiiittle hotter perhaps than the early releases but very well done.
I have never heard the box set.
Nucleus should be namechecked more often in the handful of bands that were at the very beginnings of jazz/rock and or fusion
