There are lots of people who use Razer mouses considering they are a pretty big name in the peripheral industry and there are mixed reviews. There are those who absolutely love the product and there's the people who may have received a dud mouse or may find that their mouses feel "tacky". Considering that demand for Razer products have gone up over the past couple of years, quality control has gone down leaving many people with faulty mouses, you can find many articles on the lifespan of Razer mouses, such as the DeathAdder.
I personally have the Logitech G500s, a step up from yours, and it feels amazing! I particularly like the hyper scrolling feature. It also fits my hand well as I do have rather large hands.
It all comes down what you like the look of and how comfortable it feels for you, therefore, I would recommend going to a local PC store and trying out different mouses. Also keep in mind that there are different types of mouses for different types of grips.
Let us know how it turns out and good luck.
