I have neck seal problems (pretty lean guy) when I turn my neck even slightly. With the silicone neck seal and bioseal, they've largely disappeared, whereas before they were only reduced with the bioseal. I fully agree with @stuartv in that the silicone seal is a million times easier to get on consistently right. And for 58 pounds through Seaskin, it doesn't break the bank. Finally, my past drysuit's neoprene seal did get ripped a little. Not enough to do any damage to the seal's effectiveness, but enough to use some aquaseal to repair it. Not saying that silicone is right for everyone, but I'm pretty confident in my choice.
