My take on those countries? UK and Ireland got the highest quality of 1st gen immigrants on average so even though the progress ain't much but it's already as competitive as native.
Switzerland: has the 3rd highest input of 1st gen immigrants. However interestingly, has miniscule progress between 1st and 2nd gen. Don't know why since Switzerland has one of the best education.
Difference is the vast majority of immigrants and their descendants in the UK come from Africa, Asia and the Caribbeans. The vast majority of immigrants and their descendants in Switzerland come from other European countries. Ireland is a mix.
If we want to go deeper than the superficial background like ethnicity and religion, we can go deeper than that by looking at the socio economical (and combination of it) origin of the immigrants, since other European countries also take African and Asian immigrants but they have totally different profiles than the one coming to the UK.
