They all use very similar technologies, so when it comes down to comparing similar models from different companies, it's really the feel and extra features that separate them.
My preferences in order from best to worst:
- Razer - the original gaming mice, very slim, low profile, variety of design.
- Logitech - near-perfection and stylish, and very good software.
- Microsoft - known for being the most ergonomic/comfortable.
- Saitek - technology on par with Logitech/Microsoft but designs are too weird and uncomfortable for me.
Plus, if you're a hardcore GW fan, Razer made a special GW edition of their mouse.

Where have you read this, and what do you mean by dying?
I've had my Razer mouse for at least 4 years now, and it's still in good condition. Razer make all their mice corded, which is important for the best response time; as most wireless mice go into a standby mode to save battery power.
Oh, and this razer mouse guide is somewhat informative for mice in general:
