It makes the rifle muzzle heavy...and just heavy overall, that's why I prefer the SPS Tactical or LTR with the shorter barrel on a rifle that will be carried in the field or used for hunting.
(Well...that and the useless stock, but both of these points are minor and easily fixed with a little gunsmithing. Actually, just a hacksaw will do...to shorten the barrel and cut the stock into more easily disposable chunks...
Comparing ballistics, the 20" BBL gives most of what the 308 is capable of and has enough capability to reach out to 1000 yards or beyond with the right bullet/load. It puts holes in paper, but the 308 is barely squeaking by at 1000 yards at best, so the hurdle is in my brain,... why cart around that extra 6" of steel. On a 300 RUM sure...a 300 WM maybe, but for me, the plus side of a 308 is that it can be made into a smaller, lighter, handier package that is better suited for it's range capabilities.
Some just like long barrels so it is a personal choice, but not necessary for ballistic reasons.
Look up some of Montana Marine's posts for his velocity testing and his take on the matter.

There's been a few test reports on here in the last several years about the effects of barrel length on velocity. The effects are'nt huge but are somewhat sugnificant IIRC. The gain per inch decreases as more inches are added and again, IIRC, 30 to 50fps per inch is a conservative guess on the average. Maybe someone who has has done a test will jump in with facts. Anyway, all this to say, if your on the ragged edge already @ 1K like you are with a .308, every fps counts. A few inches could gain you a couple hundred very important fps.

So what your saying is the longer the barrel the more fps? </div></div>
Yes, but as you can see in el gor do's post, sometimes it aint much.

For me, every little bit counts.
