The main issue with dry gloves is that they are not very tactile. Yes you can still open small boltsnaps etc, but it's alot more 'numb' compared to using wet gloves.
These are the rubber gloves that I fit to my Kubi rings:

They are the exact same rubber gloves that came with the Kubi rings originally, from the factory. My first pair of them lasted a full year before I finally wore a pinhole in the end of the thumb on one. They are not as robust as, say, some of those Showa gloves I see some people using, but they are infinitely better tactility. If I am diving somewhere where I expect to have to hold on a lot and expecting sharp edges (e.g. a wreck, in current, covered in zebra mussels), I will put a very thin pair of gloves over the dry gloves, that have a tough PU coating on the palm and fingers. They hold up really well and protect rubber dry gloves from cuts.

The rubber dry gloves are 30 mil thickness, which is way thinner than my 3mm wet gloves. They give FAR better tactile function than my 3mm wet gloves - even with the wool glove liners I normally wear under them.
I use my dry gloves on any dry dive except in water that is so warm that I am only diving dry to have the redundant buoyancy. I.e. if the water temp is below 70F/21C and I am diving dry, then I use my dry gloves. Bonus: I can use dry gloves and still have wrist seals in place, so I have redundant protection against my suit flooding.
The Kubi ring system is very nice but I have been told by folks that use it here in belgium that they unanimously do not recommend using it with silicone seals....the thickness of the silicone seals is slightly thicker than latex and tends to become compromised/ruptured when used with the metal Kubi rings. Of course experience varies. I use the Waterproof Ultima DGS system with the si-tech oval rings.
I have been using Si Tech silicone wrist seals with Kubi rings for almost 2 years now, I think. I replaced one of them after the very first dive. My suspicion is that it got nicked by a fingernail or something when it was being installed. It tore on the first use. I haven't had to replace one since. My Kubi rings are 80mm. I suppose the ring size might affect how well the seal holds up.
If I were not using Kubi, the Scubaforce Thenar rings and the Waterproof Ultima rings are what I would be deciding between. I like the Kubi better than the Ultima, but I'm not really 100% convinced the Kubi are worth the extra expense. I think they are better, just not sure if they are THAT much better. The Thenar are unknown to me with regards to quality. I have not seen a set in person. But, the idea of them seems really nice. They are anodized aluminum, like the Kubi rings, but appear to have a better shape for being able to be streamlined, compact, and easy to fit between your body and stage bottles when trying to reach into a pocket.
Seaskin is nice, but there are very good Italian drysuits made by Rofos and Divesystems for example. With all the options a Rofos probably doesn't cost that much more.
But, if it costs more, what are you getting for the extra money? Seaskin Nova suits are not just "good for the money", they are "good", period.
Some items not yet discussed here. Pocket options, bellows or expedition? Which one are closer to current Santi or Ursuit pockets (with emphasis on handling with thick gloves)?
Would you still take all the reinforcements? Which would be your optimized minimum viable reinforcements for someone who wants to keep the suit light and flexible without compromizing durability.
I see you also opt for TLS torso. Can you comment on that more?
How did you take the measurements? I have been wondering should I pay for a tailor to get the measurements to get them right.
After having other suits with velcro-flapped pockets, I got the zippered pockets on my Seaskin and could not be more pleased with them. Now that I've had them, I definitely prefer zippered pockets to velcro flaps. I put a loop of thicker bungee through one zipper pull on each pocket and tied it with a double overhand knot. That makes it very easy to open and close them, even with gloves on.
I got the shoulder and elbow reinforcements and the Kevlar knee pads on mine. I think the PU reinforcements don't seem to make any difference to the suit's flexibility. The Kevlar doesn't really, either, but it's just on the knees. Bottom line for me: I would get just the same setup again.
I got the TLS and would do it again.
For measurements, I printed out their form and instructions and got my girlfriend to take the measurements. Worked out fine for me.
I also really like that I was able to order 1-pc coverall-style undergarments that were also made to the same measurements as the suit. My body shape needed a made-to-measure suit. I don't know why any drysuit maker would think that a MTM suit would be okay with off-the-rack undies.
