Looking for my first purchase

Hello, I’m looking to start my journey with aneros after seeing so many positive reviews from people. I looked at the buyers guide and I’m kind of stuck with a bit of indecision. Since the toy is fairly expensive (for my budget) I want to get it right the first time. Looking on the buyers guide, the helix classic and the helix syn are both recommended. Since the classic is plasic and the syn silicone I was wondering what would the recommendation for a first time user be? I have some small silicone plugs and I have difficulty using them at times because of friction despite the copious amounts of lube. Would a plastic toy be the better option or is silicone better?

Tl;Dr which is a better material for newbies plastic or silicone?
