Yeah, I think it'd be a more valid comparison to put it next to something someone would actually invest that's also international. I'm not sure if there is a similar Vanguard fund.

Edit: I think I found one — VTWSX is +35% over the same time period. Accounting for fees vs the managed fund, probably means a better return here.
