For most road drivetrains (i.e., not 26" wheels, and not tiny microdrive chain rings) 12 is a better 1st position than 11 (because it's not as unreasonably high) and in the case of the 12-36, it can easily be customized into a 13-36 simply by replacing the 1st position sprocket (and for most road drive trains with 48T chain rings or larger, a 13T 1st position gives you a more usable top gear than a 12, and at the very top end a 1 tooth gap is nicer than a 2 tooth gap). In my opinion.

Steve, I agree starting cassettes with a 12 tooth cog makes more sense for most riders.
Aeroperf and Paul, thanks for that feedback. It wasn't my intention to knock Alivio.I swapped the Deore brakes on my Atlantis for Paul Motolites with Paul levers over the summer. I would say that was a definite upgrade in terms of feel and performance. I was curious if going high end on cassette would make a similar difference in terms of feel/performance. It sounds like spending money on the rear derailleur would make more of a difference. The pricier cassette would only be lighter.
Well, some of the really high end cassettes look a lot sexier
too, but how often do you get a chance to actually take a good
look at a cassette? In terms of longevity, sometimes the cheaper
ones have an edge, if the high end ones use titanium sprockets for
lightness, as has been done in the past. Those don't last very
long.
Laing, it sounds like this is more of a problem with parts being harder to get after a booming year. Like I said I was only basing this on my LBS, who in past years was able to get most any part within a day or two, saying many 9 speed cassettes (including the 12-36) were back-ordered.
There have been supply chain disruptions with all kinds of products, even in areas (like toilet paper) where there wasn't an unanticipated bike boom on top of a pandemic.
Seriously, those Shimano 12-36 cassettes are perfectly fine.
Easier to install and remove than some of the higher end ones,
because aside from the 1st position sprocket it's all one hunk of
metal. The 12-27 has two or maybe three sets of sprockets mounted
on spiders, plus some loose sprockets and loose spacers and takes
a lot longer to R&R.
Joe, the Analog has some very tempting stuff. Not sure if I could get myself to spend that much on a cassette and then ride it through winter!

Don't even play, get yerself a 12-speed Garbaruk cassette from Analog for about $250. It comes in colors! 👍

In general the fancier cassettes are primarily lighter, usually by using multi-cog carriers, while SRAM's highest-end cassettes are almost entirely one-piece affairs. The difference in weight can be substantial, almost 1/2lb going from a 11-36t SRAM 1050>1090 (10spd), but the $/gram cost gets high, and the weight saved compared to the overall weight of a loaded touring bike + rider is pretty insubstantial.

Lots of options for 12-36 9-speed on eBay. I think the main difference in quality and price has to do with weight. Lower 'quality' cassette is going to weigh more.

There is also IRD, who makes a 12-30 and a12-34 9 speed. and a 13-38 8 speed for that matter.
Note that I just built a bike with a brand new Shimano 14-34 7 speed FREEWHEEL (Shimano actually just issued an updated model within the last year) with a twist grip indexing a Shimano Altus M310 derailleur. Parts obsolescence is not as much of a worry as some think. But I do of course have a brand new in the box 12-36 Shimano 9 speed just in case....
