Necon 777 is the generic version of Ortho 777. I was on Ortho for nearly 10 years before switching to Ortho Tri-Cyclen. I can honestly tell you that 777 was the best I'd ever been on. No weight gain, no water retention, regular but shorter periods...when I switched to Ortho TC, suddenly the weight started to pile on (10+ lbs), EVERY MONTH the water retention was horrible and it's been 2 years now and I'm sick of it so I recently switched back to the 777...Necon is the brand my insurance will cover.
Your body will decide if 777 is right for you. I know you posted this a long time ago and may not even be around reading but I saw the thread (new here) and thought I'd share.
