I'm having trouble getting my point across but basically what I'm saying is that most of my time is spent thinking. The coding part is small and as long as the IDE is not batshit crazy I kind be just as productive in any IDE.
I will admit that there is one IDE that I like the best but I wouldn't argue that I'm able to finish projects twice as fast with it than with any other reasonable IDE's.
And yes, XCode, Eclipse, Android Studio are more or less the same.
Glad to hear though, I'll try it for my next android project.
Also, not to belittle your investment in Eclipse, but counting university is laughable and unless you're a maestro and use some random plugins that make you a 10x developer you're probably better off switching.
As others have mentioned you can change your keymap to Eclipse, or just learn new ones. Hell, I only know 4 keystrokes: autocomplete, find class by name/click, rename variable/method, and reformat code. Yet somehow I am successful -- I doubt it's my IDE. It's just effortless and I don't have to deal with stupid build crap while writing code. Granted, I don't know much about modern Eclipse, I haven't used it for two years.
If it weren't too much effort I'd be writing java in vim where I have almost 8 years experience, but I haven't gotten around to bothering because my environment is not the bottleneck to writing good code. It's probably more the crappy Android APIs and unexpected behaviors of standard libs that will unlikely be timely fixed.
