One that consistently keeps good time, unlike the FreeStyle that I have. Of course, it hasn't helped that I wear it while doing construction work.
What else do you like to do on this board besides ask & answer questions? Yes, you can plan trips with other divers, discuss the latest sports news, dissect the latest diving accident, but questions, answers to them, & oftimes the internet brawls that result are a major part of this board. What is the problem with that? If you don't like the fact that someone asked a question, you don't have to answer. I am not interested in photography (YET), so I don't visit that section of the board. I don't have an interest in getting a tattoo, so I don't view threads concerning them. I am not a sports fan, so I don't pay any attention to those types of threads either.
Bottom line, if you don't like answering newbie questions, don't. You use this board for one particulsr set of reasons, others will have different reasons than you do. Live & let live, & help someone who doesn't know as much as you out from time to time (if you feel like doing so).
