In any case, I always like to try out a few alternative software choices before I settle with any particular application mainly for two reasons: One, you would never know how good or bad the one you are using is until you try some alternatives and two: a bit of choice and competition can only be for the good of us users! Your motivation might be different: perhaps you want to find a free software that does the same task as the paid software you are using or maybe your favorite Windows application is not available on Mac or Linux.
