Very interested in the 6.8 western and what it's capable of ballistic wise. That being said availability of components is a real thing to consider at this point and 270 components should be easy to acquire in comparison. With a fast twist barrel the 270 should be able to push 165 gr bullets with high bc's about as fast as the 6.8. This would be for a mountain rifle type build, and though I'm interested in lightweight the long vs. short action really doesn't influence my decision. And lastly I'm a handloader so factory offerings in ammo also doesn't influence my opinion.
What would you choose?

6.8 Western is closer to the .270 WSM. It is just the WSM case shortened .08" and a faster twist barrel. I'd probably chose the cartridge based on what I can fit in the magazine for COAL and still feed. Your magazine length will be your biggest limitation for either rifle, but the Western design at least took that into consideration.
While .270 components might be plentiful, will the heavy for caliber high BC bullets 165+ be plentiful or seasonal? I'm sure 6.5, 7mm, and .308 will always have more options for high BC bullets. Manufacturers are starting to offer high BC 6.8/.277 bullets, but they have a long way to go to catch up to the others.
Now I'm a die hard .270 Win guy, love it and it'll be the one cartridge I'll always own. I don't see much need to improve on it, and its proven track record. I've found it to be quite capable with the bullets that work in a 1:10 twist well beyond 400 yards.
It'll also depend on if you're building or buying. If you want an off the shelf rifle the 6.8 Western will be the easiest to aquire. You're simply going to have to build the .270 Win to get what you want.
Far, far, away in a distant galaxie is the 6.8 Western!
This makes absolutely no sense, the 6.8 is just a .270 WSM with the right twist. It's a correction of a mistake Winchester made when they SAAMI standardized the .270 WSM IMO. I think it's akin to what Nosler did with the .280 AI, fixing the .280 Remington crappy SAAMI specs.
If high BC bullets are the priority, I would think using the same case size but going to 7MM or 6.5 would be wise: much larger high BC bullet selections. Why not a 6.5/06 (or 6.5 WSM). or 280, 280AI, 7Mag,,,all with fast twist?
If you do decide to go the 6.8 Western route, put out some feelers for brass to see what you can find. Personally, I could have bought more Winchester 6.8 Western brass in the past three months than any other brass on the market, locally.

Nothing so far addresses the fact that a 270 a 270 WSM seat the bullet deep into the powder column. The 6.8 Western along with the appropriate barrel throat keeps the bullet base at the neck of case so there is more space for powder and less turbulence when things are burning.
Been thinking of doing this for years. Let me know how it turns out.

While this has been written by a few "gun writers" because, apparently, it is in the press release they used to write their articles, do the math and you'll see it's not true. In fact it's blatant nonsense. The 270 WSM and the 6.8 Western cases are identical except that the WSM's shoulder is .08" further forward. almost a tenth of an inch MORE powder capacity in the case. It and the 6.8 Western typically come in a rifle with a 3" (or a hair more) magazine box. So both will be loaded to the same OAL by the handloader. The .270 WSM has more powder capacity. And take a look at the length of the bullets that go in the 6.8 Western. Even if loaded to absolute SAAMI max OAL, the base of the Sierra 175 TGK (1.641" long) sits over one tenth of an inch below the base of the 6.8 Western's neck. At SAMMI min OAL, it's 0.3" below the base of the neck. At the same OAL, the 270 WSM with have the same bullet seated .08" further below the base of the neck, but that bullet shank will be surrounded by powder that the 6.8 Western, being a shorter case, just can't hold. Load to the same pressure, the .270 WSM goes faster. No offense - it's just math.
In a hunting rifle ( not long range target) I cannot imagine that amount of turbulence would effect accuracy once the bullet has left the barrel and has been stabilized by the grooves and rotation. I should clarify, effect to a degree which is detrimental on the gun's ability to kill game at normal hunting ranges.

Will do, but it will be awhile. Barrel is 4-6 months out, fortunately I have an Echols Legend stock already. But my gunsmith has been really backed up lately.

What would you choose?
Had the idea for a long-loaded (3.600" M.C.O.A.L.), 1:8 twist .270 Win, using the 6.8 Western throat, to go on a long magazine M700.
It would seat the 150 gr. to the base of the neck, like a 130 gr. in a std. .270 Win., and the 165's half way to the shoulder, like a std. .270 Win./150 gr.
Should push the 150 gr. ABLR at ~ 3,000 fps, and stabilize the 165 gr. ABLR at > 2,850.
At this point I can only recommend both barrels. If this were me Id expect that If I had both to choose from the lesser capacity 270 win with the long throat & fast twist would would get put to service much more if I had both to choose from. YMMV
