Modern C# is a powerful and compelling language; C# vs. C++ on that front is an open debate... one the internet has a great number of easily found topics on.

The old runtime unity uses, despite using newer class libraries and so on from the open source C# stuff from microsoft... well, its terrible. I mean, its usable, but its like C# lite, with none of the features or optimizations from you know, the past 5 years.

C++11 in UE4 is hands down better. C++14 will be even better.

...but their tooling sucks at the moment. Right now, despite the unity runtime, its still a better system to work with as a developer.

In the future, who knows?

Maybe unity will use a new version of C#? (deeply unlikely)

Maybe the UE4 tooling will improve a lot? (very likely)

My advice is 'watch this space'; the UE4 engine has great potential, but right now, despite the good parts, the bad parts are so bad I couldn't recommend using it professionally.

...but hey. Thats just my oppinion. Its free. Download it and try it for yourself. If nothing else, the code is a facinating read in C++ learning.

Actually they will upgrade Mono when IL2CPP is stable enough.

Cool! It makes me change my opinion on the whole Unity vs Xamarin.

Thanks for sharing.

I am quite comfortable with both languages, just lack the time to do anything and was curious about the experience from someone about both engines.

I do share your opinion.
