I must say that I spected a lot more from Yoshitoki, even more after revealing his ghoul nature. At least we know Tsuneyoshi is more dangerous but Yoshi being killed like that did not bring a good impression over the Washuu, the "Final boss".
Anyway, putting the leaders aside we cannot judge V`s power just because some agents that faced Eto were "fodderized" (if some black suit guys took down the One-Eyed Owl I would rage quit)

.
We have to remember that V has ghouls in its lines too, Kuzen being one of them and he had to run away when he was a topclass ghoul.
Does V have more "Arimas" and powerful ghouls in its lines? I think that has to be true because if its not the whole plan of Arima to bring a proper King would be so pointless... and I dont think Ishida would let such a plot hole slip like that.
Eto falling against Furuta didn`t seem that bad for me, after all he is a One-eyed superhuman hybrid with suppahyped Rize`s kagune!
I just want a good explanation of how he got in the clown gang without being a ghoul (?) and when did he pass the surgery.
