I like tahoe pretty well. it does require more than a little digging in to find if the programs you use often will be able to run under the new OS.
if you don't run anything specialized (like ... video or image editing software or something very specific and only us the browsers/normaltools, I'd do the upgrade. I think you'll be able to revert back to sequoia if you find you need to.
,but that'd be something to look into as well. make sure you have a good timemachine vault and backups near to hand.
