If you are going to use it for hunting and will be toting it around then go with the 20 inch, But if you are using it from a stationary position where weight dosen't matter go with the 26 it never hurts to have a little extra.

If you not hunting go with the 26" I have never owned a tactical rifle so to speak that has had anything less than a 26" barrel I have own a rem 700P in 308 and my current is a savage model 12 with a 26" tube in 308. I just finished a shooting school in PA. where several students were useing 20" 308 and hitting steel out to 1000Y. Its not imposible I just prefer a longer barrel. I dont use mine for tactical shoots or matches or police work, so I think the speed gain over the weight of 6" of barrel weight is worth it.
