Those specs you quoted are pretty much identical to Citizen/Bridgelux, as far as typical values go. +/-6% is good, have you seen a list of binning codes? They mention it, I saw no specifics.
Hopefully they are good, this whole generation is moving up a notch in efficiency, but if they are more expensive in small numbers, they will have a hard time finding traction for DIYers.

Neither of us has any idea what variation in flux really looks like in the real world, and again, on paper they are about the same.
I'd like to see how they bin, though.

Please take another look at the datasheet: typical performance at 140 watts: 17770 for 3500k 80 cri= 127lum/w @ nominal power. At Tj=85, not Tc.
The thing that gets me avout this one is that it appears as having a redpeak above the standard 630nm on high cri which somebody might like. But it might be my morning eyes being blind. Also low price in bulk but diy quantities are 40ish at mouser. Digikey 300 moq
Worth putting under a par meter at least

Yeah this is "gen 3", which I don't actually see for sale anywhere. Didn't look super hard though.

Binning:
CXM-32-35-80-54-AC30-F4-3-ND
F4 is the flux bin, but all chips in this gen seems to be binned F4, even though the lums vary between temp and cri. Less helpfull...

seems on point, somewhere between cree DB bin and a CLU058 on paper. ill snag one when digikey has stock and run it through the mill, the price is right

loving these cheap chips that are schooling cree lately, hopefully they come out swinging with their new series. blows my mind that citizen is only 4 mos away from something better than they have now. kinda makes you wonder what all these companies are hiding on their test benches. im sure there is a lot of great tech that hangs out while they clear out old stock and get the most out of the money they put into manufacturing infrastructure

Nice find bassman! Heres the datasheet.

THIS. It's why smaller companies are more agile than large ones.

I almost bought some o those, but ended up with CXB3590s.
I have 6 CXA3070s 3000K in the back, and 6 CXB3590s in front.
I run 4 plants 2 back 2 ront, and after 2 runs the back plants always yield more.
So the question is, is it the cobs or something else?
Seems like the CXA yield more.
Im running them at the same power, 1 driver for back and one driver or front.
Ill definately let you know what I think of them, and post pics

are they both 3000k or are the 3590's the normal 3500k ? maybe more reflective walls in the back row?
