Reflection performance on Xamarin

I have seen this and many similar posts and blogs across the net saying reflection performance penalty isn't noticeable. I also have seen posts like this one claiming (rightfully in my mind) that reflection is extra code running impacting performance noticeably. Let's imagine for a moment that you can write code that is cleaner using reflection or a bit longer and more complex code without it. Which one would you choose?

This is the question in my mind. As a particular example I'm talking about O/RM, MVVM helper and IoC containers that use reflection.

Should I use Prism for example? That makes the code much cleaner but uses A LOT of reflection or not?

And last but not least is the performance of reflection any different in Xamarin and mobile platforms in contrast with desktop and native Windows platforms?
