It's hard to keep it up-to-date without instruments to measure efficiency of pieces for each slot in an objective way.
Sims are too slow for that (and there are none available).
The spreadsheet is way too outdated.
We can parse stuff sure, but there are so many variables in there and FFXI has no "puppets" to measure DPS efficiently that way.
So yeah...
In terms of TP gear there really hasn't been any major changes in years. Outside of crazy DM augs on Chironic BRD still relies on the same gear.
Ayanmo+2 is basically pretty close to any other option and offers good acc and DT with minimum effort.
Ashera Harness is clearly a body ugprade but alas not everyone can claim to have one.
Bastok Volte Hands/Legs/Feet too are nice upgrades but hard to obtain.
Volte Legs and Jokushu Haidate are nice pieces to put in the legs slot (higher than usual haste values) to compensate for other slots if you get crazy DM augs on Chironic (they have low haste, so you need a slot with bigger-than-usual haste values to compensate. Legs is a perfect slot for that).
Linos is your friend for TP and WS.
Rings have the same options between Moonlight (hybrid/DT), Ilabrat (STP/acc/attack), Petrov and Hetairoi, they're all pretty close and it depends on what sort of builds you're trying to make up.
BRD doesn't get many options and the outcome changes according to your buffs and builds but
generally speaking Aeneas and Twashtar MH will favor multiattack, whereas Carnwenhan MH builds will favor MA with AM3 down and STP with AM3 up.
This is a general rule but it doesn't apply to every slot, every piece and every situation, it kinda depends on many factors.
Even SJ wise /NIN vs /DNC is hard to compare.
Former offers the additional layer of defense through Utsusemi and 1 more tier of DW, it's generally more straightforward to use.
The latter offers slightly more acc, 1 more PDL tier, lots of debuffs/tools that go well if you wanna play "support DD" hybrid role instead of focusing on pure DPS after you sang your songs.
WS gear is pretty much the same too.
Lustratio+1 is nice for Rudra but dangerous if you get hit in it.
Ayanmo+2 is a nice starting point for mules or people who don't want to bother too much.
Relic+3 is sorta BiS for Mordant Rime and can be good for other WSs as well (like Rudra) when you're attack-starved. Body is of course sorta BiS for pretty much everything.
Really, that's BRD summed up in a simple way, there hasn't been any huge update to BRD gearing paradygms in years alas.
