What are the major differences between Altus, Acera, Alivio cassettes? This is for my Fuji Traverse which is just a hybrid/recreational bike for me. For my type of riding will I notice smoother/quieter shifting to even bother? I picked up some new front/rear Deore shifters and derailluers and was thinking for a few bucks more should I replace the Altus cassette at the same time?

Thanks for any input.
