All projects are equally important, some to maintain high ranks, others to push all the way up to the high ranks.
Each member is free to run the project(s) he/she most likes. Some people prefer the health oriented projects to benefit mankind in the future, others would like to find aliens out there and others (like me) prefer more uncommon projects like Pirates and Burp. lol
So my advice would be for you to dedicate yourself to the project(s) that pleases you the most. Or you can check on the DC matrix the most optimized projects for your machines and really stomp us in those.
What really matters is that we all have fun while crunching.
