I have several autos...my favorite is a Microtech Combat Troodon. It's an out the front and a bit on the expensive side {$450.00.} One of the best for the money is the Uzi, at around $75.00. Pretty high quality and holds an edge well, it is a swing out type.
The above being said, no swithcblade or auto is as fast as a folder with the Emerson wave feature. It pops the blade out when you are taking the knife out of your pocket. Many Spyderco's can be had with this feature {my every day carry is a waved Endura} and unlike most autos that are illegal to carry most places a folder that is waved is not. An auto has to be pulled out or drawn and you have to find the button and push it, with a waved folder you simply pull the knife out and the blade is opened and ready. Autos are illegal to carry in the communist democrat state I live in, not even with a CCW. They are not illegal to own though and I have several.
