Silicone seals are purported to be more comfortable than latex but they are easier to tear. Personally, I don't find them more comfortable.3rd dive on my seaskin today and I ripped a wrist seal when I took it off. I thought silicon was going to be better than my previous latex.
I had a glued-in latex neck seal on my Santi which lasted for 3 years before it got gummy and needed to be replaced. I got the Si-tech Quick Neck installed because I didn't like being without the suit while the seal was replaced, but I don't think the silicone neck seal is more comfortable. In fact, I think it is a little more prone to chafe my neck (although I'm pretty resistant to that compared to others). But it is nice to know that if I tear the neck seal I can field-replace it. I have the same neck ring in my Seaskin Nova. But in reality, I had a lot of warning before the neck seal on the Santi needed to be replaced.
I have latex seals in my Santi wrist rings and started out with silicone in the Seaskin. But I tore one of the Seaskin wrist seals and replaced it with latex... because they are cheaper and I don't think the silicone seals are any more comfortable.
I think going forward I'm going to go back to latex. They do get gummy and stretched over time, but they are cheaper and less prone to tear. Just my 2c.
Ps, try using water based lube to lube up the seals both putting them on and taking them off. It will make them less easy to tear. I take a travel shampoo bottle of lube in my dive kit. It is less messy than talc and you can use it when you are taking the suit off, whereas talc doesn't work well when you are wet. I just use generic KY from Amazon, it is pretty cheap. And watch your fingernails.
