I stayed with the MS441 rather than the MS461 or MS660 due to the anti-vibe. It is worth it to me.
I would have gone with a 461 but I wanted a Mtronic saw. The 461 is not much less than a 660. The 441 is a smooth running saw. It is the Rolls Royce of chainsaws. I think the 661 had better A/V than the 660.
