I've owned every V2 Atlas made including all the LE versions as well as the Dark Forge Reaper, Wraith, etc. I'm assuming your comments are in regards to Dark Forge as Venom, Rafferty, and Infinity are demonstrably better fit and Atlas themselves have stated Rafferty and Venom make better guns from largely Atlas parts (per Adam). Infinity is its own thing given Brandon has extreme OCD around controlling the process so they make everything in house including all the small parts. I forget if that even includes their springs. Something not even Atlas did until recently.
As for Dark Forge, the Kovert Reaper (ported and comped) absolutely outshoots any current V3 Atlas in terms of splits or return just given the physics of ported and comped versus no such current analogue until the Hades production version releases Q4 2026 or Q1 of 2027. Dark Forge is more hit or miss, but I've not been impressed with V3 Atlas fitment and I've probably handled 20 different guns at this point across various V3 models. Coatings, barrel lockup, trigger fit, disconnector issues, slide to frame fit was sloppy on some. I'd generally give Atlas the edge as they have a more refined production process, but they've been pushing heavily the past year further and further into their emphasis on tight tolerance CNC machining to reduce or minimize how much hand fitment and QC assembly requires. Per Adam those numbers are down a decent amount, even if there are still plenty of hours put in.
Dark Forge is Rogue. They've been around, they did/do plenty of white label work for the likes of TTI and other similar brands like Cardinal/Optimum were providing parts for Atlas. Sure you can argue their fitment isn't as good on average, but shoot the Ported and Comped reaper off a ransom rest against an Erebus or Apollo and see for yourself. I sure have. I've also run them back-to-back with plenty of GM buddies who agree that it's close, but the ported and comped reaper is easier to return, faster to return, and has less felt recoil. The Hades beats the reaper by a tiny bit, and all of this is splitting hairs, but it's there. Now, whether a shooter has the skill or experience to tell those minute differences is a whole other matter.
