As said above the situation is the following:
Bmb will arrive earlier with potential QC problems. Better painted imho generally I don't dislike the overall shape.
Zeta will arrive later with worse paint job but generally with better shape and potentially less qc problems.
Price is quite high for both and does not justify the choice between the two,so my personal judgement should be to wait for Zeta reviews before po some of them.

 

From what I can see

Zeta pros :
Nicely proportioned Torso
Better Jet mode
Much better legs
Cleaner and accurate back
Slightly thicker arms
Possibly better QC

BMB pros :
Much better wings
Accurate kibble behind the shoulder
Cockpit is lower than Zeta so the face is more visible
Paint job
Possibly cheaper

 

I would add the cockpit in robot more on zeta is too high and covers the face

 

Oh yeah right. Added!

both look good but I’m leaning towards zeta at the moment

 

And don't forget removable missiles on Zeta. One of the reviewer said missiles on TW can't be detached.

 

Woah really? Man, that sucks  

 

I wish they'd change the wings. Nowhere near as good as the other one. They should just straight up put those wings onto this mold. I prefer how the other one looks but the wings being on tiny ball joints is turning me off, and I'd trust Zeta's QC more.

 

Yeah, BMB wins with the lower front windshield and the wings. But everything else is totally outclassed by Zeta. Yes, even the paint. BMB looks like someone went crazy with a black panel liner and it REALLY stands out. Zeta in comparison looks far more natural. Sometimes, less is more.

 

Transcript from the Thunder Warrior review. Looks like the missiles can be removed but the missile holder can't.

 

BMB's has more accurate markings----USAF instead of "UFOAF", and actual US Insignias.

 

Yeah, sorry guys, I think he was just talking about the big one that can't be removed.

 

You mean those Fuel tanks?

 

I don't know. This is based on my memory but he called them missiles. I'll double check after work.

 

Wow....
*starts saving some money*

 

Yeah, I really really don't like how Zeta does the weird made up insignias on their jets, including their aerialbots but it's even more egregious here on what should be a more real world looking model.

 

I really hope it comes with that flight stand. That being said it looks great. I'm going to wait until both get reviewed before I spend money on one.

 

I think overall Zeta looks more "natural" and better proportioned but I have a hard time choosing. This is worse than BMB vs WJ MPM-08 ko "war"  

 

Another pro I give to Zeta is that it looks like it may include that cool looking flight stand for the figure.

 

A small point, but zeta's is actually worse in jet mode when it comes to the canopy---they've "painted over" some of the glass on the side.
