I was looking into adding one, some or all of the above mentioned titles to my pull list. I was hoping to get some feedback from the community on the merits of these books. Much Appreciated!

Aquaman and Justice League of America are the best of that group. I'd rank them:

JLA

Aquaman

Hal Jordan/Flash/Green Lanterns

Cyborg

Flash has been a solid book for the writing, but rough to look at until recently.

Aquaman continues to be a top book from DC. More politically inclined, with Arthur spending much of the book dealing with diplomats and foreign powers, but there's a lot of action too.

Cyborg is hit and miss. The Imitation of Life dragged on and sort of still hasn't ended. It's a lot of world building, which Cyborg has desperately needed. The book is more fleshing out his supporting cast and introducing new members of it which are also hit and miss. The villains are getting progressively better for the most part. Overall, it's not terrible, but I preferred his New 52 book. This isn't too bad and might be worth a read in trade before adding to your pull list.

I've only read the first trade of The Flash and Aquaman from the titles you've listed.

The Flash is really good, although like mentioned above the art is a little more sketchy than I would have liked. It's definitely worth reading though.

Aquaman is one of my favourite heroes, but the first trade was pretty bad. One man's meat is another man's poison, I guess, because as I've lamented at length in the Aquaman forum, I found the political nonsense a real Phantom Menace style turn-off. I'm hoping the under sea adventures resume once the politicians have adjourned their endless boardroom meetings and negotiations.

Green Lanterns-It has it's moments. Most recent issue was pretty cool.

Hal Jordan & the Green Lanterns-Love it. Worth the pickup.

Flash-This is doing great so far, worth checking out.

Cyborg-Personally wasn't a fan, dropped it.

Aquaman-Hadn't been reading until a few weeks ago because I'd heard too many good things. So far it's good.

Justice League of America-Second issue just came out today so it's hard to tell how it'll be, but it's looking promising. I mean, Lobo is in it. What more do you need than the Main Man?!
