If you like science of cooking you might enjoy Cooking Issues/Dave Arnold quite a bit more. I generally prefer Dave's cut of the jib.
But Dave Arnold's slogan is "you're an enemy of quality", a title you can obtain by doing almost anything differently than he might, including not precisely measuring the displacement of ice and water before mixing a G&T. He calls things "garbage products" all the time. He is far, far more opinionated than Kenji is.
If Dave's opinionated demeanor isn't a problem for you, then opinionation (is that a word?) isn't really your problem with Kenji.
I highly, highly, highly recommend Arnold's book, Liquid Intelligence.
Cooking Issues is fundamentally a podcast about failures and attempts first and foremost, so it tends to skew a bit more towards scientific method I suppose.

Skip to around 13:30, at the marker "Hose discussion becomes rant" (I assume Nastassia wrote that). He's not kidding. (He's often kidding about "enemy of quality", but sometimes he isn't, and it's a far blunter thing to say than anything Kenji has said.)
I love him so much.
He is opinionated, but explains why he does things (often offering a scientific reasoning/experiment), especially if he's not following the traditional way, he seems to give context on what would be more traditional, and is quick in communicating "but you do you"...
