[Q] SlimBean 4.3 or not?

Please tell me the disadvantages of having SlimBean 4.3 rom over the official rom. I want to make sure it would be worth the upgrade. I am on a very fine 4.1.2 official rooted n7000.

Would I be able to easily install and update apps like Whatsapp, FpSE etc on SlimBean 4.3 rom just like I do on official 4.1.2 rom?
