Ok I actually had to make an account just because this post was... wow.
3C is pretty unsafe if it whiffs, yeah. But you only throw it out in combos or if you know they'll block it. And seeing as how 3C can chain into stance besides 236D, I don't see how it's unsafe. If they block it and think they'll get a free punish, DP. If they see you stance and expect the DP, you wait and either go out of it or do overhead/low cause guess what... they're safe! And overhead catches jumping opponents so they either have to block, get hit or mash blindly.
Hotenjin isn't the best reversal in the game but it is top 5. 214DB isn't a great reversal but a great move in general. It's a DP that's safe on block against most of the cast and can lead into a 2-4K combo on CH with decent meter gain. Even on regular hit, Lvl 2 214DB can lead into Hotenjin for 3-5K damage.
He never said 623D was a great anti-air. Just that it was another usable anti-air, which it is. Not to mention that both of you forgot that 2A, 5B and 5C all anti-air extremely well too.
What the hell? Unless you're completely predictable about using stance moves, throwing out 214DA is stupidly good anytime. It's a safe overhead. It's a SAFE overhead. Lvl 2 even allows him pressure since it's +8.
And this is where I decided I had to post. Hazama's mixup game is terrible. Cool. Time to go to the frame data!
6A is 22 frames ( about average overhead speed ) and -5 on block, meaning you either need a 5 frame poke or to IB it. Except if spaced right, your 5 frame poke will whiff if regular blocked, so you need to IB it every time to get a punish. And I don't see the problem with it only being able to combo into Hotenjin at all.
6B is a standing low, 25 frames, kinda slow. Except you see Hazama standing so you expect an overhead. Not to mention it's -2 on block, meaning you need to IB to get any sort of punish which won't happen if spaced correctly. Again, only leads to Hotenjin, don't see a problem with that.
214DA is 19 frames, +2 LVL 1, +8 LVL 2. Moves you forward. Don't even need to say anything else.
214DC is 19 frames, -3 LVL 1, -1 LVL 2. Need to IB LVL 1 and have a long range 5-6 frame poke; good luck punishing that!
Hazama's command throw has the same limitations as Bangs... like.. being untechable? A good mixup option? Hazama's is faster by 1 frame, has invinciblity during command throw, deals about 2K damage on half the cast and nets Hazama 30-35% meter while the other half takes 2.7K ( which is A Tager Buster damage ) and gets 49-51% meter.
This is the only right part of the post pretty much. The person you did quote was completely right about why Hazama is top 3 though.
