Personally, I think 'Gone Tomorrow' is among the best. It has a really interesting premise. Reacher is faced with a situation where he has to figure out who the bad guys are in a very dangerous and complex scenario. The plot twists keep you on your toes and the character development is great throughout the story.
I think you should start with 'Jack Reacher'. It gives a good overall impression of the character. Tom Cruise does a decent job of bringing Reacher to life in this movie. The action scenes are exciting and it follows a classic mystery plot that is easy to follow.
Some people might prefer to start with the most popular ones, like 'One Shot' which was also made into a movie. But I think a chronological order based on the publication date is best. This allows you to experience Jack Reacher's growth and the changes in the writing style of Lee Child, the author. For example, in the earlier novels, you might notice a certain rawness in the character's portrayal that gradually becomes more refined as the series progresses.
