Looking to buy new mouse, what should I go for?

Choosing a good mouse isn't the easiest.

Indeed, normal mice can do the trick, but I must admit I've gotten very used to have different macros one different profiles depending on the game I play.
Or the enjoyable fit that a certain mouse gives me. Or if there are a few well-placed side buttons that are great for most games to have.
But most importantly, it's if it has been a durable product over the years.

And albeit the the reviews aren't shining for the Razer Mamba, I purchased one 5 years ago, and it's still rocking with only some very minor bug every few months. The thing has traveled in my backpack quite a bit too.
