I would say Deadman's or mine - I'm launching seven attacks plus at least two that he cannot block and will go through his armour, and have a strong layered defence with lots of dice behind it.
Deadman is doing basically the same thing, the main difference is his plan uses a Spark Bomb to get through without Contested Movement (which I'm slightly nervous of), and I use Slice-Aside Tricks which then chain into our Basic Attacks, whilst he's using Hefty Halter Chop.
I'll note that HHC potentially disarms him, which is self evidently great. Better than another Basic Attack, IMO.
Fair enough, I did forget that one, but it's more like, all the Firebomb Strikes which don't have enough dice to get through any kind of defence.
Like, with Basic Attacks I can see the logic in terms of wearing down defences because they're very cheap and generate Stoked Dice - but Firebomb Strikes are not that cheap, and don't get us anything. Also with how the attack system works in this game, every attack we make is inviting another attack until we run out and the turn ends. So throwing a lot of weak attacks whilst not having sufficient defences... can be asking to be hit a lot.
So, Alectai's plan seems to be relying on him being, basically, out of defenses by then, having wasted all of his on the first 6 basic attacks and their Sword Strike follow-ups. So the Firebomb Strikes would, in the world where that works, be relatively unopposed. I'm...fairly dubious of relying on that personally, but it's not impossible by any means.
And making more attacks doesn't subject you to more attacks. One person running out of attacks is not a round end, inherently, that's when both people have run out of attacks. Like, if nothing stopped it, and one person made 10 attacks and the other made 60, at the same speed, they'd trade attacks for 10 exchanges and then the guy with 50 extra attacks would make their remaining 50 unopposed. That's...very unlikely to happen, as IME, well over 80% of rounds have a round break before anyone is actually out of attacks, but it could happen in theory.
Oh, speaking of Basic Attacks, can the Basic Attacks in my/your plan right now actually hurt him if we presuppose one got through and hit his armour? If not, what do I need to add to make that happen?
Because Slice-Aside actually stops him from using his sword to defend if it wins, and then launches a Basic Attack as a followup, so in my plan it's not impossible in my plan that he'll get hit with some.
So, the basic attacks both our plans have on offense could definitely hurt him if they hit, yeah. Assuming that his armor wasn't pierced, they'd do 4 damage to it and it'd get Pierced after three of them. So each individually isn't huge, but they matter and he does need to actually defend against them.
Whether the ones from Slice Aside work is actually a trickier question. Basically, you need to spend over Rebuke in Orthstirr on an attack for the attack to get through it. So...does the Orthstirr spent on Slice Aside itself count for that, or is that only counted as part of the defense not the counterattack? If it counts on the attack, they work, if not, they do literally nothing.
Which way does that actually work? We have no idea. Which is why I'm reluctant to use Slice Aside in this fight.
