In a bolt gun, go with either, I don't agree with cheaper necessarily these days, but I have not shopped o6 in a while. If it is plentiful in your area, and cheap, then buy a bunch of ammo and let that be your guide. The main reason I go for .308/7.62x51, is efficiency over the o6, meaning less powder for the same performance, availability, which is no longer true, except in my loading room, and much more load development has been done, compared to the 06, mainly due to popularity and match shooting, not to mention, it's use in sniping has driven every manufacturer to develop a Quote MATCH LOAD, in several weights, 155, 168, and 175 mainly. And in a tactical, less penetrating round like Hornady Tap 125's. In a semi-auto, not much o6 to chose from in a tactical, or battle rifle other than the garand, unless the new FN allows it.
Nothing wrong with the old girl, she's just been replaced with faster, lighter more efficient cartridges, I would not sell one to upgrade if I had one I liked, I got rid of mine years ago, including a really rare battle rifle, a Danish Madsen, it was in immaculate condition and fun to shoot, but let it go. It was made for the Columbian Government by Madsen, features a short stock with recoil pad, and muzzle break that did work. Peep sight and stripper clip loading.
