Yes, rollers tend to be better than a fixed trainer. The slight angular changes relieve overloading we see on a fixed trainer setup. This is especially try with motion rollers that add the fore-aft motion.
Long story short, I made my first rocker plate after a season training on motion rollers. I wanted to switch to a smart trainer, and hated the return to no motion. I made my rocker plate to give some of the freedom of the rollers, but be easier to ride overall (especially at the hard efforts and intervals).
Rockers can be tuned to have lots of support or be about as loose as rollers, without the risk of riding off them. Could be worth a look and I can cover more if you’d like.
