Valiant.
The new VEI universe which reboots the old Valiant characters from the 90's is pretty good.
I highly recommend Archer & Armstrong. It's a comedic adventure title with strong conspiracy theory elements, and an Indiana Jones vibe. It starts off a bit slow but by the end of issue 24 it's become absolutely brilliant (and the only reason it starts off slow is due to set up which is paid off later on).
X-O Manowar is a decent book, which combines the man in the armor aspect of Iron Man and man out of time aspect of Captain America, with a healthy dose of alien threat element and whatnot.
Bloodshot is good if you like ultra violent, military industrial type stories.
Harbinger is fantastic. It has a slight X-Men vibe but is wholly it's own thing. A much more realistic and hard hitting approach to examining people with super powers than most books in that vein.
Shadowman is a supernatural horror book with a strong element of voodoo. If you ever liked the late 80's and early 90's Vertigo titles like Sandman, you might enjoy Shadowman. It's probably my personal least favorite Valiant title, but that's only because I'm not big on supernatural stuff.
Unity is a team book (sort of Valiant's version of Avengers or Justice League), bringing characters from X-O Manowar, Harbinger, and Archer & Armstrong together, specifically Aric (X-O), Livewire (Harbinger), Eternal Warrior (A&A), and Ninjak (X-O). It's first arc was ok but I loved the second arc, featured a pretty original villain and his plan was interesting.
Quantum & Woody is strictly a comedic book, but it's reliably hilarious. Not very deep or interesting characters or storylines, but it's always good for humor.
Eternal Warrior is another decent book, focusing on the brother of Aram from A&A (both of whom are immortal). The first arc was mediocre, but I loved the second arc which takes place in 4001 AD and has a Lone Wolf and Cub influence.
Rai is a stunningly beautiful book with amazing artwork by Clayton Crain, focusing also on the 4001 AD era in Neo-Japan. It has a Blade Runner mashed with samurai vibe, and it's story is both interesting and great set-up for future arcs. But Crain's artwork alone is reason enough to buy the book.
Then there are crossover mini series like Harbinger Wars, Armor Hunters, The Delinquents, etc.
