Hello! i am debating which control panel out of those three i can use also, if anyone knows where i can get cheap licenses for those control panels then please also post them here.

You can do a search for it.

plesk there's one place to get it from plesk.com. Plesk if by far prefered by clients, althought it lacks some features admin features that most admins would like but hopefully it will come in the futre.,

If you compare Plesk, Ensim and CPanel I can always say cpanel is pretty good with masive features.....Cpanel has got many good features and the advantage is like that will get update everyday automatically.....which you wont be getting with any other cps...and plesk thats ok....but again that doesn't have the features like cpanel....if you are looking at the price then go for plesk...but never go for Plesk..but I wont be suggesting you that too....always go for cpanel
