My fatbike has a low of 22x36. Not as low as it looks as the 3.8 inch tires make for a larger diameter. Have thought of making it a 42t in rear. Just because.
On the Sam Hillborne, until last fall the bike was a 1x9 with 39t up front and 11-36 in back. Only changed it because I would be climbing some hills that were very steep for short pitches and wanted a lower gear. In retrospect, could have gotten by without it. In fact, as the bike is indoors this winter will probably change it back to the 1x9. Just easier to deal with for the vast majority of my riding. As for high gears, have rarely used my highest gear, no matter the bike. Might have shifted to the 11t cog on the Hillborne a couple of times. But in those cases it would have to be a downhill with a tailwind. And even then would probably just coast.
