I shot some Hornady 109 ELDM and Berger 109 Hybrid from a 20" Carbon Six barrel last weekend. Over 34 grains of Varget, they were running 2897 and 2899 respectively.

I use the short wheels for anything shorter than 308. U can use the std wheels but u will get some heat on them.
That's some solid velocity for a 20in! I told my smith to finish the lt palma at 21", should be around 3.2# or so. This will be the side piece truck slut laying in wait for unknowing vermin around the farm.
What is everyone running for varget on a lower node for 105-108 grain? I find for the higher 2950ish fps anything past 34 gr is pushing it a bit. 32-33 range seems it but I haven’t gotten it definitively pinned down yet. I want to try and hit a 2800-2850 node for practice and maybe matches.
I second what @LR1845 said, 600y benchrest/f class is dominated by 6br variants. I really like the 6bra with lapua brass.
With 33 grains you should be close to that, I’m at 34 grains of varget with Berger 108’s out of a 26” barrel with mv of 2920
Thought I was taking it easy with 105 Hybrids and 33.5 grains of Varget out of a 26 inch barrel. 2904 fps.
Ya, I third what 406 and LR1845 are saying. I am currently running a 6GT and it has been great, learned a lot with it, I have shot some really good groups with it. However I am currently in the process of building a Dasher. They are just better suited for going down the road you are on.
But back to your original question between 6GT and 6 creed, my vote is 6GT, has been easy to load, components are becoming more and more available everyday. 32.6 of varget and a 105 Berg Hyb was an easy button for me in the low category of 2850ish.
The 32-33gn range is probably it for 2800-2850fps (depending on whether you've got a faster or slower barrel). I've run a shitload of Shooters World Precision Rifle (basically slightly slower Varget) in the GT, and 32gn nets me ~2760fps, 33gn nets me 2805fps with a 106 A-Tip.
FWIW and sort of related, I no longer believe case-fill is as big of a deal as some make it out to be in order to get low SDs, but I do sort of believe there is something magical about using the faster burning Varget-like powders (SWPR, N140, N150, etc).
Ever since I got an Ingenuity Precision trickler and all my ammo has been loaded with charges always within +/- a single kernel of each other, when using SWPR or Varget, everything shoots, and I haven't seen an SD over 20 shots that wasn't in the single digits in ~2+ years now.
I even started experimenting with my 6CM barrels and have been running a load that hammers that just about any old fudd would tell you is completely wrong: a heavier 112gn MB with only 36gn of SWPR in 6CM, the cases are maybe 3/4 full and sound like salt and pepper shakers when I shake them... straight-up hammers, and my SDs average ~7 over 20 shots.
I’m in the boat also. I shoot my 6.5cm at 40.5g of h4350 ant 2700 ish and seat them long with a COAL of 2.90. Hammers and I sounds like a salt shaker also with sd’s in the 6-8 range always.
When I get my gt up and running I’ll do the same with that catridge. 2750-2800
Depending on the characteristics of the barrel I've run 31.5 - 32.5 which has put me in the 2830 range from 26" barrels using 108 and 109 bergers and 110 A-tips.
H4350 and some of the others in that burn range are no slouches... but I'm drinking the Kool-Aid on using the faster Varget-alike powders in the 6GT. Less powder means less recoil (easier to spot splash/impacts) and the faster powders just make things easy.
This is 33gn Shooters World Precision Rifle under a 106gn A-Tip, average 100 group is ~.3" (hammers out to 1250 yards too):
