Thinking of switching to the Skyla after being on the pill for 2.5+ years...how did you like it?

I've been thinking of switching to the Skyla for a while. I've been on the pill microgestin for over 2 1/2 years. Should I make the switch? Is it worth it? What changes did you notice when you switched? The pill made me gain weight (getting that under control now) and super moody sometimes before my period, which is another reason why I kinda want to switch. Does the Skyla ever give you mood swings? Any thoughts, opinions and experiences are welcome! And TIA! :)
