I used and tested all of the mentioned parking services (and few more like parking palace etc) and they all have some adv and disadv.
I would group them as google api, without it and rotation parkings . (for beginner domainer with 10-500 domains)
Most revenue from traffic You will get from 1st group:
Afternic, Voodoo, ParkingCrew, Uniregistry, Godaddy(afternic You need to pay for it don't recommend at all)
but this group is most risky for "black domains" I mean if Your domain get traffic from bots and "sh... traffic exchangers or proxies" You will probably get ban sooner or later. This mean You need to take care of Your domain and be sure of good traffic source. Maybe it's better for domainers with 1000+ domains i don't know need to ask some big players here
.
2nd group: non google here traffic source is not that important (not means that You will not get ban for invalid clicks or some back actions). Bodis, Sedo, theparkingplace, ParkLogic
In this group You will get max 1/10 for clicks compared with 1st group.
3th group: rotation parking here You have some parking services which using other parking services with their api. Most of actions is automatic here. You just add domain and script searching information about it history and put Your domain on specific parking for example voodoo or sedo. Sometimes it needs register on other parkings like it is on above. For this group you have: above and DomainPower and ParkLogic.
