Parked for sure. I'm f**king amazed of my stats, 2x more clicks due to very relevant content, 3-4x more CPC for expensive keyword domains (for example I got 0,8$ instead of 0,12-0,16EUR) then with SEDO.
Also migration was fast, I've added bulk list of domains, changed DNS and about 80% of domains got well picked keywords from domain name, other 20% I've edited in few minutes. 50 domains parked really fast.
System also have awesome parked page content for 2 keyword combinations, sometimes it works well with 3 keywords.
Also every page have suggestions how will change CONTENT keywords, when you choose this or that keyword combination.
I love PARKED. I love PARKED. I love PARKED.
