Pretty sure it's a Stiller tac 30 built to APR's spec, Not certain but it looks like it. nothing new under the sun there, it's a 700 clone. Price is pretty good.

It boils down to what you want or are looking for. There's a ton of good actions out there and there's a lot of good coatings and treatments out there. DLC is OK, but definitely not at the top of my list. BTDT and I'd take a good Nitrided action any day over one that is DLC.

Specifically compared to the TL3, well the TL3 offers a lot of differences that may or may not be a big plus over the APR G2 depending on what you're looking for most notably the ability to change bolt heads and an integral recoil lug. The other differences are controlled feed, and mechanical ejector vs a push feed and spring ejector in the G2. Also a bayonet style fire control group on the TL3 which is nice for cleaning, but can present problems from time to time. Beyond that I mean it's a 700 clone vs a different 700 clone.

$1250 for a TL3 and $825 for the APR G2 Both reputable companies so nothing to worry about there. If you're looking to cut some costs the G2 would be the better option. If looking for the best action there's far better than either out there.

If you're down for the higher price tag, I'd strongly advise adding $100-150 to the budget and go with a Lone peak Fuzion or an Impact 737R. I own both and have owned Bighorns in the past and I can tell you 100% than the TL3 doesn't compete with either when the rubber meats the road when it comes to smooth operation, especially in dirty conditions. There's also some weak points in the TL3 that, should you have an obstructed barrel or other catastrophic failure, allow the bolt to leave the receiver at high speed. I know nobody plans for that, but a very accomplished and normally safe shooter I know got complacent and distracted and took a TL3 bolt to the face that probably wouldn't have happened with a 1-piece bolt design.

Just food for thought.
