The biggest difference in the two barrels is the bullet weight range you can use. The tighter the twist, the heavier/longer bullet you can use as the expense of losing the ability to shoot lighter/shorter bullets. Between the two that you are looking at, there won't be a huge difference.
Longevity wise, both should hold up about the same. I believe the difference in the rifling comes down to the 5R being more fouling resistant because its more of a pyramid shape than a square cut. If I'm wrong, someone will come by and correct me.
