What about sites like bitvisitor, freedigitalmoney and freebitcoins.appspot are those fake? or do you aqually recive Bitcoins?

I have tried all of those at one time or another, and they do work. However, as people have said, the payments tend to taper off. Thankfully, there are many bots that work for sites of that kind, so you don't have to waste any of your time on them.

One thing you should not use to "mine" Bitcoin is bitcoinplus.com. It was flagged as a site that downloads malware in the past by Google SafeSearch, and see this post: https://bitcointalk.org/index.php?topic=38283.0 for why it's a massive waste of your time and CPU power.

Having said that, are CPU or GPU miners more efficient in general?

In general, it goes ASIC -> FPGA -> GPU -> CPU
