In other news, it would appear that the augments for Tenryu Body and Feet were added to BGwiki. So, we now at least know what the added stat is on each piece.
I have listed the augment to the right of each piece's name, and included the base stats of the unaugmented piece below each item. I am in no way responsible for being the primary source of any of this information, and am merely posting the summary of what all of the contributors on the wiki have found.
Honor Augments
Tenryu Somen +1 AUGMENT = Haste +6~7%
DEF:36 STR+9 AGI+9 Accuracy+12 Attack+12 "Subtle Blow"+10
Tenryu Domaru +1 AUGMENT = Double Attack 4~5% (Confirmed that 5% is the HQ, thus NQ is more than likely 4%)
DEF:63 STR+9 AGI+9 Accuracy+20 Evasion+10 "Store TP"+8
Tenryu Tekko +1 AUGMENT = Double Attack +1~2%
DEF:30 STR+8 AGI+8 Accuracy+10 Attack+10 "Subtle Blow"+7 Haste+4%
Tenryu Hakama +1 AUGMENT = Weapon Skill Damage +2~3%
DEF:50 STR+8 DEX+8 AGI+8 Accuracy+12 Attack+12 "Store TP"+6
Tenryu Sune-Ate +1 AUGMENT = Haste +3~4%
DEF:28 STR+7 AGI+7 Attack+13 Evasion+8 Enmity+8
Head/Hands/Legs immediately stand out. I can't see the body ousting thaumus, nor do I see the feet ousting the +45 base damage on kick attacks from AF3+2 unless the haste on these feet somehow facilitates a more profitable gear swap elsewhere that I haven't thought of. I have a tough time imagining that could be possible though given the 18% haste between BB/AF3+2 legs, and the haste available on Tenryu head/hands. I'm on the fence between Tenryu legs vs. Khepri legs(Which can also be augmented with WSD+2-3%). As long as you are certain accuracy is capped, the Khepri win, but its becoming more difficult to be certain of this given the evasion of legion mobs, arch-omega, and what I assume will be the case for future mobs.
Once you cancel out similar stats (calculated for 1 hander), the comparison between Tenryu+1/Khepri+1/Thaumas ends up being (All accuracy/attack boosts are accounted for from STR/DEX; when STR/DEX landed on an odd number, I rounded down).
Thaumas Kecks
(2 pieces) HP+40 STR+3 AGI+11, MND+2 Accuracy+9 Attack+3, Evasion+1 Haste+6%
(3 pieces) HP+40 STR+6 DEX+3 AGI+14, MND+5 Accuracy+10 Attack+5 Haste+6%
Tenryu
DEX+6 AGI+8 Accuracy+10, "Store TP"+6, WSD+2~3%
Khepri
STR+4 DEX+10 Evasion+1 "Subtle Blow"+8, Haste+5%
