If you are a switch hound like me and you want something that feels a cut above the rest then Unicomp new model M or ROG RX whatever the fuck.

Model Ms are so well regarded I don't need to tell you about them and why they feel good.

ROG RX switches are a new optoelectric thing that just so happens to be extremely smooth, stable, and binding resistant while combining full travel and a long pole style bottom out. The clickies also use a unique click mechanism that is most similar to space invaders and works really well if you aren't into linears. Also comes with on the fly macro recording which is always a plus.
