Personally, holding out for SkyUI sorting. I have a feeling that it's sorting function will be completed via SKSE. Better Sorting and such mods are rife to conflict with many mods that make changes to items/weps/armor/etc...
I loaded the "Ultimate" single file version of Better Sorting by eclips3 and loaded it near the bottom of my load order. Ran it through TES5Edit for conflict detection and and as expected, overwrote all the "balance" changes introduced by other mods, so I dumped it.
Lots and lots of compatibility patches would have to be created, even for mods such as the USKP. A mod trumping USKP changes for the sake of better organizing? I'll deal with the unsorted lists and keep my fixes.
