Overall, rollers will be quieter than a trainer. Less mass flinging around. Less mechanical noise.

If you're new or tentative, look for "parabolic" rollers, like these.

They are darned near impossible to ride off of them with the flared lip. But as someone who HAS ridden off regular rollers, I can attest to the fact that...it's not that bad. Really. Not the end of the world. Didn't crash. Stayed upright. Didn't rocket forward into the wall (or t.v.).

Rollers are much more gentle to your bike. They have much better and more real "road feel." And they help to make you a better, more efficient rider.
