I did my own spreadsheet on the warlock after seeing Treantmonk's video. I also have some updated fighter and barbarian charts to compare with. I haven't updated other classes to compare with.
First, this is what I see for the warlock:

Eldritch Blast is the blue line at the bottom. It includes Hex and Agonizing Blast. This is what Treantmonk usually uses as his "baseline" for damage. I'm not sure if it exactly matches his, but it looked pretty close when I compared against what was shown in the video.
I took out the GWM feat for the Pact of the Blade builds, because I agree that the warlock doesn't meet the prerequisites. I also didn't attempt to figure out how to include Eldritch Smite.
The red line is Pact of the Blade
without Spirit Shroud. The green line is
with Spirit Shroud.
Pact of the Blade build: Greatsword (Graze), Hex, Pact of the Blade, Thirsting Blade, Lifedrinker.
Spirit Shroud does 1d8 per hit at level 5, and 2d8 at level 9. This assumes Spirit Shroud and Hex and Lifedrinker all stack. No effort was made to deal with the conflict in the use of bonus actions between casting Spirit Shroud and moving Hex.
Here is a (edit: obsolete) graph to compare the warlock data with some barbarian and Champion fighter data:

Details of the different curves:
- Barb PAM Reck — Berserker barbarian using Reckless Attack with a PAM build. This is the highest damage I've gotten so far.
- Barb PAM No Reck — Same Berserker, but not using Reckless Attack. This curve is on par with the Champion PAM build.
- Barb Tank Tree — A build with no damage feats, using a battleaxe+shield for tanking, and no Reckless Attack. World Tree subclass, so no subclass damage features either. Lowest damage output, to help bracket the range of possible damage.
- Champ UA PAM — Champion fighter with a PAM build similar to the barbarian. This appears to be a midline in damage.
- Warlock Blast — This is the Eldritch Blast warlock build. Treantmonk's baseline.
- Warlock Blade — This is the Pact of the Blade build from the earlier chart. It is roughly on par with the Champion build.
- Warlock Blade+Shroud — This is the Pact of the Blade build including Spirit Shroud. This almost matches the Berserker using Reckless Attack at level 11, although it remains flat from then on while the Berserker continues to improve.
Assuming the Champion is a reasonable mid-range target for a martial type, the Pact of the Blade warlock hits that pretty well, as long as you don't deal with Spirit Shroud.
Being midline, but with the potential for massive burst damage with Eldritch Smite, seems perfectly fine. Being top-line (with Spirit Shroud) and having that same burst potential does not seem fine. Overall, I think the Pact of the Blade options are good when considered within the class itself, but Spirit Shroud definitely needs to be removed from warlock's spell list.
If you want to see the spreadsheet I used to generate these, it's available on Google Drive
here. This is just a copy as it currently stands, since I'm constantly working on the real version. There's a bunch of stuff in there, so PM me if you're having trouble figuring it out, or find a bug.
