Shimano cassette differences?
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.

Functionally, they'll all work the same. Spending more bucks primarily gets you a flashier coating. At least at the 8-speed level, it looks like the cogs all have the same amount/size of lightening holes, so the weights probably aren't too different, either.

Functionally, you'd be hard pressed to see any difference.
I'll buy 2 "cheap" ones of slightly different combinations for Winter/Summer use. Slightly lower geared in the Winter when I'm bundled up and am in worse cycling condition.

Thanks for the replies,
One of the other reasons was that maybe I could go with some different gearing at the same time. I'm here in Fl with mostly paved/MUP riding 85%/15% hard pack trails. I don't know how much difference I can make with just the cassette but maybe some chain ring changes up front too? I'm currently at 11-32D 9 speed in the rear and 48/36/26 up front. I'd like a little more speed for the pavement.

Thanks. I can get a new Alivio cassette for $20ish. The Traverse already has an Altus cassette, Acera crank, front derailluer, shifters and a Deore rear derailluer. I probably wouldn't be upgrading but I found the Deore shifters and front and rear derailluers for a great price. All brand new and the latest revisions. I'm thinking while I have everything apart why not spend the extra $20ish for a new cassette and maybe change the gearing if I can benefit from it? From what I paid for the Deore parts and if I get the Alivio cassette, I'd have under $100 into the whole upgrade. I'll put my lightly used parts on eBay to make back $20-$30 of that.

You could take the opportunity to buy a much tighter geared cassette that would give you smaller gaps in the interior gears. An 11x23 or 11x25 should still give a plenty low low gear and a better gear progression.
BTW, your current 48x11 high gear is 118 gear-inches with 700c wheels or 113 gear-inches with 26" wheels. Either is good for over 30 mph at a cadence of 90 rpm. Unless you are a VERY strong rider this should be plenty.

Your low gear seems excessively low for an area as flat as Florida. It's almost as low as what loaded tourists in hilly country would have.

That's good to know I'm doing the best I can up front with the chain ring sizes. So if I'm looking at 11x23 or 11x25 I'll need to be looking at Tiagra stuff I guess to get 9 speed? Will a Tiagra cassette work with my basically MTB other components OK? What should I go with in terms of 11x23 or 11x25? I never use my low gears. In fact I even thought about going single speed/X1 up front.

Yes a Tiagra, or any Shimano road cassette, will work fine with your MTB components. I'm not surprised you never use your low gears and an 11x23 9-speed cassette should give you an excellent choice of gears with a low gear way beyond anything Florida requires.
Years ago I had a bike I kept at a friend's house in Orlando that was geared 50/40/30 chainrings and had a 13x21 7-speed cassette. I never needed the 30T chainring and that cassette gave me a "straight block" (1 tooth cog differences) from 13 through 17T. Even "Sugar Loaf Mountain Road" never needed the lowest gear and there were no downhills requiring a tall high gear.

So if I go with the Tiagra 11x25 will I be giving up my top speed? I found a new Tiagra HG50 11x25 for $30 and a new Deore HG50 11-32 or 11x34 for $30. Hmmm.

An 11T smallest cog is an 11T smallest cog no matter what's behind it. There will be absolutely no change in the speed you can get in your top gear.
Again, the Deore and HG50 cassettes provide low gears you have absolutely no need for, they give up useful interior cogs. You said you never use your low gears so why duplicate what you know is useless to you. Go with the Tiagra.

Edit: I think that's an Amazon typo and the 11x25 they have listed as a Deore is actually a Tiagra. Aren't they the same equivalent level wise meaning the Tiagra road line is the same as the Deore level MTB line?
Edit 2: Just snagged the Tiagra 11-25 for $23
