Too hard to tell, going by the bottom Reddit post there are some discrepancies, but he is also using the older, but more 'premium', Caster XPG. The Lancer kits are newer, and they have both Samsung and Hynix ICs, but you won't know what you are getting when ordering. You can look this up on their website with the part number decoder IIRC.
Hynix loves AMD, AMD loves Hynix. The person also uses an MSI B650 Tomahawk, which was a board that didn't like all memory. I don't know whether BIOS updates resolved this, but it was a board that contributed to the Zen 4 instability debate.
Here is also a thread on Overclockers:
As I mentioned earlier, the ADATA kit could run at CL30 while previously reviewed G.Skill couldn't even boot below CL32 at DDR5-6000+ and up to 1.60V. I'm not sure if it's a matter of used motherboard - ASUS Strix Z690-I Gaming or something else but DDR5-6800 was barely booting and was crashing randomly even in the AIDA64 benchmark.
I will try to rerun some tests once I get a better motherboard.
The ADATA XMP Lancer memory is one of the best options right now because of the lower price than the competitive series and great overclocking results. Even though I couldn't set it at DDR5-6800 then results at up to DDR5-6600 are pretty good and can be tuned further.
Granted, that is with Intel.
Comparing the two G.Skill kits:
32GB x 2 (64GB)
Trident Z5 Neo RGB DDR5-6000 CL30-40-40-96 1.40V 64GB (2x32GB) Intel XMP / AMD EXPO

F5-6000J3040G32GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-6000 CL30-40-40-96 1.40V
64GB (2x32GB)
AMD EXPO
and
16GB x 2 (32GB)
Trident Z5 Neo RGB DDR5-6400 CL30-39-39-102 1.40V 32GB (2x16GB) AMD EXPO
www.gskill.com
F5-6400J3039G16GX2-TZ5NR
Trident Z5 Neo RGB
DDR5-6400 CL30-39-39-102 1.40V
32GB (2x16GB)
AMD EXPO
It is worth noting that the advertised specs are EXPO and not standard. The SPD speed and voltage are set at:
A buyer best have a stable setup. Though I don't think this is an issue any more though I have seen some reviewers having issues with the Gigabyte 800 series boards specced lower than the Master. The RAM is massively overclocked, and I am sure a BIOS revision has already addressed this. Regardless, instabilities are noted, but nowhere close to what it was when AM5 made its debut.
ADATA don't say much about their XPG RAM, the Lancer is simply rated:

32GB
6000MT/s 32GB CL 30-40-40 1.35V
They don't add whether this is with XMP or EXPO. Note that they don't advertise the tRAS. I don't know whether this has to do with the IC. tRAS is debatable in any case, since lower isn't always worse, and higher isn't always better. Though we don't live in the 1333 days any more.
I came across this unknown reviewer who does have a comparative test, looking at a synthetic gaming bench:
We take a look back at the ADATA XPG LANCER DDR5-6000, this time around we have the C30 version of the kit we reviewed at the start of the year. Let's see how it perform in this review!

I can't say how reliable that bench is, but that is crazy. The system is a 7950X running on a ROG Strix X670-E.
All this said I do have the G.Skill set I have posted. I got it because I knew what IC I would be getting, but I wanted to get the XPG set to do benchmarks though it got sold out within the same window I wanted to purchase it.
