I had no doubt that it was, I guess my post was more that they have both been around for a bit doing close to the same task. So for the people pretending this is "Gnome abandoning things like they always do" I think it's kind of silly to not expect a "default" app that is more than 7+ years old to be replaced with something newer.
Especially because these are the "default" apps that I would expect to be replaced once someone learns the DE and outgrows the defaults.
True, and as long as expense ratios are the same or lower than your US index/mutual fund then your only real issue is if the US market rebounds and outperforms your portfolio if you had diversified more.
And the expense ratio's can vary a lot. For example Fidelity shows the exp. ratio of ($0.08 per $1,000) 0.008% for their Index Equity Fund, where their International Equity Fund has an exp. ratio of ($4.02 per $1,000) 0.402%.
