Coming at you with a Comixology Sale, they’re promoting Suicide Squad and Justice League as there’s an upcoming crossover between the two coming this December. I haven’t read the DC Rebirth titles for Justice League and Suicide Squad but I can recommend the recent New 52 runs for Justice League and Suicide Squad.
If you’re looking for something older, check out the JLA series on that page. You have creators like Grant Morrison, Mark Waid, Oscar Jimenez, Howard Porter, and Bryan Hitch on that series. Its a really good run on the Justice League of America and still holds up.
