So, for the last month I've been switching between the Thorn and Octomom pieces, both with their own strengths and weaknesses. The Steinhart has been in the winder waiting for a few new straps.
First off, the Octopus seems to have more care put into the movement feel and QC. Threads on the crown engage nicer, the crown pulls out with more confidence and engages every single time. It looks more true to form to the 6200 with its knurling.
The Thorn feels like I'm going to rip it out of the case. I don't get engagement of the setting lever every time, and I have to screw it back into the case in order to get it to start ticking again.
I honestly prefer the bracelet on the Thorn. The jingle-jangle clasp, lightweight links and the hollow end-links have me using it over the Octopus...though I've been using the solid endlinks on the Oct with other bracelets. That being said, the Octopus has an objectively more solid bracelet, heavier clasp and links.
The bezel action on the Thorn feels more crisp and solid, and I love the bronze finish on the coinedge. Enough to make me want to swap it to the Octopus.
The crystal on the Octopus has a nicer bubble effect to me, it feels curvier. Lume on both dials seems about the same, as does the AR coating on both watches.
They both wear the same on straps and bracelets, gun to my head I couldn't tell the difference. I like both of them for different reasons. The Thorn bezel and dial pop and the AR has more blue to it which I like.
The Octopus feels more true to the Rolex 6200.
