Have you checked to see what YOU actually like first ? Go to a shop and compare passive to active...Moreover if you do a simple search you will find plenty of threads...simply asking which is best will not give you the answers you need....it will merely open floodgates of people debating which THEY think is best.
there are plenty of threads on this subject if you look through the forum..opening another will only lead to floods of fans of each tech reposting the same stuff again. The post above is good advice, go and have a look at both technologies for yourself and decide that way what best for you.
