Yes, the 2600MHz 2G6 are much less desirable than the 3200MHz 3G2.
Things change, and look a bit different from when I bought back in July.
I bought MTA18ADF2G72AZ-3G2A1.

I too was extremely uncomfortable buying from taobao.
I DMed several members here that had bought from them successfully and I took the leap of faith and was extremely pleased with how nice and quick the acquisition went!
The purchase experience went fairly smoothly: I bought 4 on 2021/07/07 for $367 and by 7/12 I had confirmed pictures of the coveted "D9WFL e-die", and then it cost me $22 to DHL them to me, and I got them on 7/15. $97.63 each total, overall still a lot cheaper than the $125 each price that was never going to be in stock in the US!
I don't see any MTA18ADF2G72AZ-3G2A1 available on SuperBuy anymore.
I don't know what the MTA18ADF4G72AZ-3G2B2TG are.
The only ones I see today are MTA18ADF2G72AZ-3G2E1:

I don't know what those are either.
Sorry.
You could always try those and when you get the confirmation picture reject them if the individual chips are not "D9WFL" e-dies.
Good luck!
