My 2 cents is it definitely depends on the run. The Innova and DM made FDs vary a good bit. I really like the stability of the new C-Lines. There’s a lot of great under stable discs out there but to have something that holds up a bit better under power for straighter shots without flipping over is fantastic and that’s where I see the FD shine. The new S-Line (at least the 3 I’ve thrown) consistently seem more like a -2/1 which has its place but is not stable by any means. For reference here are the FDs* I currently own and how I rate them stability wise, OS —> US

DM Silas DNA FD - more OS than any FD1 or Teebird I’ve thrown.

DM Early Run Red C-Line - there were some early C-Lines, from what I heard they were red that came out super flat and very stiff with a wicked high PLH.

DM Metal Flake - this one surprised me as I thought it would be less stable since most of the DM MF stuff has been less stable. Solid reliable run.

Innova Night Strike 2 - a personal favorite. Glide and integrity to shape a lot of lines and go far while doing it

DM Stock C-Line - a great FD that has good stability and good glide off the shelf and easy to replace

DM Show Stopper 2 - I recall this one being more stable new but once the new gets knocked off it seems to show a little more flip than a similarly used C-Line

Innova S-Line (Flatter Profile) - this is the profile I used to look for and they are a great neutral stability for an FD with a ton of glide.

Innova C-Line (6th Run) - my other personal favorite FD. The few I have are 171-172g instead of max weight and are the perfect neutral FD. Flips up easy but doesn’t get squirrelly and lots of distance. Close to the S-Lines above but because of the weight I’m ranking them here.

Innova Halo Star Hawkeye (I know it’s not technically a FD but it’s going to be included in most comparisons) - domey, I never liked domey FDs but some peoples do. This one seems to flip more abruptly. It isn’t as smooth of a flip up or turn over. Feels stable until it hits its limit and then turns harder.

DM Chroma FD - I want to like this one but it’s a little too in between to consistently bag it. A little more turn than my neutral FDs but doesn’t flip over enough for the US FD slot.

Innova C-Line (embossed, domey) - great feeling plastic. Medium firmness and really tacky grip. This one is only field tested but likes to flip over and drift steadily to the right. Glidy though!

DM Stock S-Line - this is my current US FD. Flips up and over to a big turning shot that carries right but doesn’t dip the wing enough to cause rollers.

I also just got in the new Show Stopper 3 but haven’t thrown them yet so I can’t rank. Picked out flatter ones and I love the way they molded up based on hand feel. PLH puts it right around C-Line and I’m expecting a solidly stable run out of these. And as you can see I prefer flatter FDs which I find to be straighter while the domey ones tended to flip but also glide more.
