You could go observe them in court and see what you think of how they handle themselves; you can go to the law library, see if either is publishing or teaching CLE's. After that? Its really the one who makes you feel reasonably confident that they can help you and are worth the fee you will pay.

I agree with the previous answer. In the end you need to chose an attorney you feel comfortable with and who you believe will fight for you. Meet with them in person to get a feel for how the interact with clients, and then watch them in court.
Felonies and DUIs are two very different animals. They happen in different courts, with different prosecutors and different judges. There are a number of well-qualified attorneys in Bellingham/Whatcom county who would be able to handle both cases competently. Ultimately, you need to do your research, meet with a number of attorneys, and then trust your instincts about which attorney gives you the greatest sense of trust and confidence.
Another resource for checking out how accomplished a DUI attorney is to check the National College for DUI Defense(NCDD) There are a number of astonishingly good Washington attorneys listed there. I know some of them personally but you are ultimately the one who has to know--and make the right decision. You're doing your homework so keep up the good work.
