We pretty much shun "voting threads", i.e., "which is the best" threads. (See Charter.)
Every time I see a voting thread about domain parking I see posts by the fanboys and fangirls of each parking company. No clear winner.
My advice is to move your domains around the various parking firms and see how they perform with each.
If you search "domain parking" or "domain monetization" you will find a number of alternatives.
DomainSponsor, Fabulous, Sedo, Parked, HitFarm, TrafficClub, and Trafficz are all popular. Depending on the volume and commercial quality of the traffic you bring to the service you can negotiate rev share.
