Never seen acrylic one but is acrylic warmer than cotton, i imagine so.
Acrylic is essentially artificial cashmere. Very fine synthetic threads, and it's warm and soft. I find it lacks the temperature regulation real wools have, so it's always hot, where real protein fibers actually adjust how much heat they hold with the temperature- they won't hold as much heat in if it's warm where you are. That's great for going in and out of buildings in the winter. Artificial fibers can't do that yet. I'm sure somebody's working on it, but they can't. They're also not absorbent, so if you sweat they won't pull the moisture off, it'll stay with your shirt and you'll feel somewhat sticky. Wool can absorb a pretty good amount of water before it starts to feel wet and loses it's effectiveness in heating you. Also, acrylic is often really, really bad with static electricity.
Acrylic is an inferior fiber in many ways, but it does have the advantage of being a fraction of the cost of natural wools. If you're on a budget, might be worth grabbing an acrylic sweater at a kohls or whatever for $15 and seeing if it works alright for you.
