I've got GODLIKE.
Setting? Awesomesauce. It's very interesting, flavorful, and gripping ... but it's hard to really mess up WWII, in some ways.
Mechanics? Crap.
The One-Roll idea is elegant, simple, and quite interesting to read. At the table, the four groups I've tried it for, all thought it was crap. Everybody is rolling piles of dice and trying to figure out what the turn order resolves to ... some powers are obviously better than others, etc etc.
To some extent it is fun, and certainly playable, but not for much more than one-shots. Lethality is appropriately extreme, so without some sort of powerful soak ability your tricked out hero is as likely to get torn in half by an MG42 as the fifteen grunts trailing behind you.
Which is awesome and setting-appropriate and fitting with the tone and flavor.
But relatively unawesome in any kind of game you want continuing characters in. It seems to rapidly devolve into "What Interesting Way Can I Get My Character Horribly Maimed?" Much like CoC and insanity.
The stress mechanic is relatively awesome (Cool), and plays well with the system. I built one character that was a dead-eye shot with super-Cool who was just an inhuman killing machine. Which tended to play out better than any other character concept (I.E. instead of going for "Super Hero" and getting opened to horrible maiming and death when I tried to bust out the "Super Hero" factor, I just made a preternaturally effective SOLDIER and played him like any other guy in WWII ... just ... better. Which worked out too well, since it left guys with super strength and bullet proof pantaloons feeling overshadowed by John Q. Grunt who happened to shoot well and wasn't afraid to die.)
On the whole I'm not disappointed I bought the book. I've run several great one-shot adventures with it and the read was worth the cover price (marked down). For a similar genre game where folks want to keep their characters through several arcs, my group has used Blood And Vigilance on top of d20Modern in the past, and just used the genre information from GODLIKE.
Oh ... there's one mechanic in there I DID love and thought about trying to incorporate elsewhere.
The super-powers function, basically, on the BELIEF that their super powers will work. Characters can then bid points of belief to try and shout down or suppress other super powers in their LoS. "I believe I'm better than you." And, of course, if you LOSE after pitting so much of your self-belief into the fight, you become weaker and could possibly stop believing you have powers at all ... and then really lose them.
