@Hedgehog was even advocating for a 3-fund portfolio, because of lowest TER and highest AUM and trading volume of these. I made a wiki post on it, there is a table which compares the 3. But the TER are no longer up to date.
Edit: I updated the table. Anyway, I don’t think that TER is the most important factor. It’s the total AUM, trading volume & total number of stocks that are more interesting.
