The gas spring also has the advantage that if anything failed the spring wouldn't go flying around, they are damped.
Spring loaded chain tensioners are fairly notorious for not working in more than one direction. There aren't exactly many successful spring loaded tensioners designs in FRC. Unless you happen to have experience in the area I wouldn't recommend something as "better" that you haven't successfully run yourself (and if you have, I'd love to hear about it).
