I have the sourcecode of LibGDX and this is what I got from my experience;
All the supported platforms are now so mature that they have absolutely perfect performance together with Cerberus-x.
You don't need to think about batching just use your common sense with textures and size and you will be so good. You will be happy with the result.
But Android, it's different you need to think very hard when you do a normal scaling of your development. It can easily surprise you in a slowdown and you might be able to find what it is or it might very difficult maybe even impossible to make the same performance.
So you might think, but Android is like that, that is how it is. Well I thought so too until I saw LibGDX in action. And not just that, it works on Android models way back, at least Android 4.4 and probably older. I would say 2012 or thereabout. LibGDX existed back then so it might actually be how most high quality games in those years, where created. What about new models? They love LibGDX as well.
Cerberus-X.. here we see a difference, older will be hard to make perfect I have found out ways to do things that I woul like to share when I'm finally figured it all out to the degree that it will be useful for a regular programmer.
New Androids they love Cerberus-X because they tend to batch and do magical things like all the other platforms (i think this is where wea re going). But it's very slow you need to have at least API 28- 30 or so to experience this. I'm not sure where they made the biggest changes that actually matters in performance but they happened around there.
Older Androids are x10 magnitude slower than the platforms and have problems. So you might say it's the OS, I would agree and say yes but libGDX goes around it and makes it as good as anything. Older devices behave like they are form this year and I am not kidding.
So libGDX, yes, absolutely worth checking in, I have the sourcecode on my drive and I'm not used to this kind of thing but it actually got me inspired. I want to say I'm impressed by Cerberus-X in large it's better than Unity in many respects. But libGDX beats both in extreme 2d games for instance and also other things.
So in short, Cerberus-X is perfect for anything absolutely anything, but not older Androids, and you can still get good there too as I said. But not what I'm doing right now.
