Recently my Mad Catz R.A.T. 5 died after several years of great service, so I found myself in the market for a new mouse. After shopping around I decided on the Razer Mamba Tournament Edition as it is a larger form factor mouse which I find more comfortable.

From a feature perspective it measures up against the R.A.T.5 as follows:

R.A.T. 5 Mamba TE
Year Released 2010 2015
DPI Adjustable up to 5600dpi Adjustable up to 16000dpi
Buttons 8 9
Connectivity Wired USB (braided cable) Wired USB (braided cable)
Weight Adjustable up to 150g 133g
Sensor Lazer 5G Lazer
Additional Features Adjustable length, Aluminium Chassis, Removable Thumb Rest RGB (Chroma, configurable)

The Mamba TE does offer a lot less as far as configurability of the mouse’s physical attributes (e.g. weight and length) is concerned, however I do find it extremely comfortable. It is fractionally lighter than the R.A.T. 5 at its heaviest configuration (17g lighter) but in all honesty I cannot feel a meaningful difference. I find that the Mamba TE does feel like a more refined product, which is to be expected with a product 5 years newer.
I loved the R.A.T.5 and I loved that it was built like a tank, however I am really enjoying the feel of the new mouse and it also looks good, especially if you enjoy RGB.
