Well, I have no experience with any of these scripts but I have heard pretty much the same things about them so it has to be true, at least to some extent. Personally, I like the tube themes from the WS and you can get good results with them but their cam plugins leave much to be desired.
However, I can recommend you in all honesty RoboScripts which has been around for more than five years. It gets new releases regularly and it also comes with a very good support that is crucial if you do not know how to code aka you can not fix any errors yourself. I have built dozens of sites with the RS and they are ranking very well. It is not like you set up the page, you are done with doing any work and now you are collecting the affiliate commission, you need to do the SEO but you also need a well written script that loads fast and is user friendly to get high rankings.
I have the whole post dedicated to how to start your own cam website step by step so everyone can do this without any difficulties:
