The body hands legs and feet replace the current "BiS" option by a small margin. Whether or not that small margin is worth the price tag and months of limbus grind to you is another question entirely.
If you already had the prior good stuff, R30 nyame, Ashera, Bunzi hands/hat, Volte legs etc. then I'd recommend you do these pieces further down the line rather than rushing them, but to each their own.
At +1 rather than +2 you're simply missing 1 STP/DT/Crit/Acc/Atk etc. per piece. The Augment of DA will remain the same
