When people ask me this question, I tell them that they need to go with the person who they feel is the best fit for them. You need to make sure you are comfortable discussing private or difficult issued that may arise in your case. You should be able to communicate effectively with the attorney as well as understand when they explain the process and information to you. If you cannot reach your attorney or they never return calls, that is not someone you want either. Finally, you should want someone who has experience with your type of case and in the jurisdiction where you are charged. At the end of the day you are relying on someone else to help get you the best result possible and you are putting your trust in that person. If you do not feel confident they are doing all they can for you, then that attorney may not be the best one for you and you should consult with some more attorneys.
