I have heard good things about the Aqua C Remora. A few ppl i talk to on here have told me it would work well for my 65gal. I have also heard good things about the coralife super skimmer. But on some reviews i read some ppl had trouble with it over flowing because they didnt change the settings. I havent heard anything about the other ones you listed.
I am a newbie and do not have a skimmer yet but im in between the two i just talked about. I think the aqua will do a surface skim?????? im not sure though.
The Coralife is a good skimmer from what i hear for the price. Hope this helped you out some
Feel free to correct me if im wrong guys
