I have 26t/28t/34t cogs I've been moving from cassette to cassette as the other cogs wear out. The big cogs rarely wear out and I like to buy cheap 12-23 12-21 and add in cogs as needed to get a nice custom spacing. I haven't ridden with a stock cassette in years. For most riders there's nothing dumber than the first 4 gears being 11-12-13-14.

Recently made my own custom 9 speed cassette for my gravel bike. Took an 11-30, tossed the 11t and added the 34t. Gearing is 12-14-16-18-20-23-26-30-34 and it is absolutely perfect for the riding I do.
