Again, it depends on the use. The Marlin will outshine the Glock in all areas except portability/carry. If "wearing" the gun is important to you the, of course, you should go with Glock. If just shooting, hunting (and even home defence), etc. is more important to you, the Marlin would be the logical choice.
FWIW, other factors to consider is that the Marlin has been discontinued for several years and will be harder to find in the future. (I've been looking for the .45 ACP version off and on for two years now.) The Marlin uses S&W magazines which seem to be in a little more abundant and less expensive than Glock magazines (at least the hi-caps) around here. Glock no longer makes/offers followers for pre-ban hi-cap magazines so maintenance might be a problem in the future.
