»Puppetmaster, like all other pet jobs, has no "best" weapon. Everything is situational. In terms of raw damage, KKK is only good when you can full time AM3. If for some reason you cannot fulltime AM3, it is not useful. Period. Overloading is essentially a non-issue at this point, so the burden- isn't really worth anything.
To be fair, the MA+50 is also pretty huge if you're not getting capped magical haste from outside buffers. Very rarely an issue when solo + trusts, but with the general state of melee these days it's certainly not inconceivable to be in a party and getting less than haste + double marches or something. For instance, do you really expect to be getting capped haste in most CP parties? Seems a lot less likely. Any time you're taking advantage of the entire MA+50, the delay reduction alone already makes KKK pretty damn strong even before accounting for aftermath (assuming you can get still get reasonable accuracy). But, yeah, obviously AM3 is the biggest draw.
Anyway, Ohtas are certainly really nice now for punching stuff if you don't have KKK - especially when you need huge Acc and/or have a DD puppet out.
But the other RMEAs deserve a mention too:
* Verethragna became pretty damn good this update with 269 skill, excellent dmg/delay (118//51), and a whopping STR+50. Plus a good associated WS in Smite. And while it only procs on first punch in a round, ODT aftermath is certainly welcome. Less AM-reliant than KKK, and while they do nothing for the puppet they're very powerful from a master perspective. And hey, can double as one of the best MNK weapons.
* Godhands are also very strong. Mainly for the insane dmg/delay (150/60) with skill+269. IDK if the lv4 SC is really worth a ton, and if you're taking good advantage of that they're even more impressive, but just on pure dmg/delay DPS it's already a beastly weapon.
And just below the RMEAs, if you happen upon a pair of Comeuppances (from Unity version Pandemonium Warden), those are also probably better than anything else you can punch with from a pure master perspective.
