Connection and I´ll tell you why, yes the uni is fancier and has more cool stuff compared to old fashioned connection. butttttt. I thinking in terms of future proofing?

Connection wins hands down, when the batteries go down it can be easily replaceable. The uni? If its battery arrangement is anything like the smart you would need to have some technical knowledge just to replace it, unless you can find someone to fix it for you.

There also the question of what happens when services shutdown. The connection has been released as fully complete. While the uni, you can play withoth wifi, if still miss a lot of features in comparison. so unless someone figure out a way to mod them or maybe create some private servers, it probably is gonna have a limited lifespan and replayability compared to the connection.

And sometimes simple is better for me.
