Since you did not list anything like what you actually like in a mouse, what it's for, or your budget, you should look for a mouse that exists. You may want to provide a bit more details or just do a web search on "how do I pick a mouse" and read some articles. Many variables in picking a mouse, first how much you can spend, size of hands, grip style you like, how many buttons you want, curved or flatter shape, wireless or wired, quite a few things to decide first before looking for advice.
Two good mice: Corsair Scimitar - Comes with 12 side buttons, although its heavy, it is durable and right handed. Logitech g203 - 2 side buttons, lower profile than the Scimitar, and lighter + cheaper as well. Right now it is overpriced but I got mine from Best Buy for $20.
