I'd take G900 over MX Master if only one mouse for gaming/productivity - responsiveness is phenomenal and smaller/lighter.

 

For productivity MX Master because of the side scroll and speed adaptive scroll.

 

Wow, that is an expensive mouse!  Getting close to NZ$200...    I currently use a G602 on my desktop, and a Performance MX each for my laptop and Cintiq Companion.  As good a the Performance series are, I have decided that Gaming mice have the edge when it comes to sensitivity and and accuracy, and they are oh so important with things like Photoshop when doing stuff like placing the points for clipping paths.  I also like the G-buttons on the G series mice, which compliment the G-keys on the G910 I use.  I just love being able to switch workspaces, and other regular functions with a single button or key press.

Where the Performance MX falls down is the centre button when pushing the wheel.  That is an essential function with SketchUp, and my G602 does it way better than the Performance MX.   I recently looked at replacing the laptop mouse for that reason, but when looking at what I'd be spending, I decided to go the whole hog and get a 3DConnexion Space Mouse.  It took several hours of use to get good with it, but by heck it is good for moving about in a 3D environment.  That does not apply to Photoshop though.  The Space Mouse is hopeless with Photoshop.

You have got me thinking with the G900 I have to say.  It looks interesting, although a bit short on buttons.  Having said that, the G602 side buttons are not all easy to hit reliably, and I tend to use the keyboard G-keys more than the most of the mice buttons, but I'd miss not having some of them.   How easy is it to switch sensitivity for instance?

BTW  While typing this I had a call from an Indian sounding person in a noisy environment offering to fix my Windows operating system.  The very first time I have been the target of that scam.  I laughed.  Told him to go forth and multiply, and hung up.
