I recently finished a game on libgdx, and had a few problems and bugs that took time to fix. I've only programmed in java and had gotten use to libgdx. I was planning on developing a second game with a friend, but he recommended using Unity.

Is it worth changing to? Considering the learning time involved.

Unity certainly does have a learning curve but once you pick it up it's not bad at all. It's designer-centric so you can get really far with making a game without writing a single line of code. And when you do need to code you can do so in C#. They also have a large helpful community and a built in asset store.

I've avoided Unity for years because the last time I used it (around 3 years ago) it was horrible and clunky, the latest 5.x version is much better and mobile friendly, so I would say give Unity a try. That said if you are more of a C++ / Lua developer then give the Marmalade SDK a try

I develop using Unity. Started using it about August last year. I have found that it is easy to get into, but has a lot of depth that provides great flexibility.

I think It more depends on type of game. Casual, simple game - libgdx, something more complicated - Unity!
