onikiri and Ubadachi vs sellsword t(win)blades

Im doing a new dex faith run of ds3 since I just lost all my save progress (thank you fromsoft for no cloud saves! :D) and sellsword twinblades L1 are way too satisfying and effective with sharp gem + lightning blade +4 especially this carried me through the dancer fight and I may use the Astora GS with sharp + lightning blade +4 situationally/ lightning infused murakumo + 8 (this is the weakest out of all of them) and whichever primary I go with I also carry the sunlight straight sword for the buff. Im already back up to the lothric prince brothers and theyre just way too agile for me to be using a GS that is doing about the same dmg as a the sunlight straight sword. Twinblades have been surprisingly useful for me just being a starter weapon but I had expected to find better twinswords at some point, it seems that most of this sub sings the praises of the sellsword blades very highly. What do yall think I oughta go with? LMK! also any other recommendations for a dex/faith build are appreciated, I can get the dark blade buff as well and really enjoyed the Astora GS and sellsword the most!
