Why Are All of The Suggestions Here for VXUS and not SPGM?

I see nearly universal support here for VXUS as an ETF to buy to have exposure to global markets. Looking at VXUS performance, it seems like a pretty poor ETF to be investing in. Sure, you get exposure to the global markets, but it seems like you probably won’t make any meaningful gains from that exposure. To make matters worse, it doesn’t pay out a dividend, so you are solely relying on the growth.

SPGM, on the other hand, has pretty solid performance. SPGM doesn’t give you as much exposure to global markets, as it seems to have a decent amount of US based companies—but that may not be a horrible thing while still getting exposure to the global markets. It is like the US allocation in SPGM is a hedge against their global holdings. Plus, it does pay a dividend.

I never see SPGM suggested here, and only VXUS. Why not? SPGM is pretty much SPY with the added bonus of having exposure to global markets.
