Does wine work or do I need cedega or there's no chance?
Any success stories?

Wine.

Never even consider Cedega, Wine is better in every case.

What're the technical differences between Cedega and Wine now anyway?  Once upon a time, back when Cedega was called "WineX", it was the only version that emulated DirectX to any useful extent, but apparently nowadays Wine can play WoW...

Is Cedega just Wine with an idiot-proof GUI frontend and preset configurations for popular games?

Yes.  Plus it costs money.

Yes. Also, everything with graphics works better with cedega. Some things work with wine too, but I can run Flashpoint with Cedega, but not with wine (as an example). I can also run Morrowind with Cedega and not with wine, but to use the Menu to ass plugins, I need to use wine.
So, the ARE differences.
