Stringjoy Vs The String Source? (Custom Sets)

Hey guys, just wondering how these two stack up against each other in terms of tone brightness, longevity etc.

On my 6-string guitars, I usually play 11-49 D'Darrio XS coated, for my 8-string, I've been using a custom Stringjoy set of 11-68. I've asked Stringjoy about whether their coated orbiters are coming in custom sets to extended range/7 + 8 string guitars and they said they are on the way soon but that was way back in June earlier this year, they are still yet to make these available so I was just seeing if anyone here had an experience with both of these strings and see how they compare? I'm thinking of trying out the string source for my next custom set order.

Apologies if this has been asked before but I couldn't find any info or other comparisons on Reddit/other forums.

Cheers
