Top 10 in Norris voting last year had 3 CHL players and 3 NCAA players : CLEAR DEVELOPMENTAL ADVANTAGE.
Top 25 forward scorers are 13-1 in favour of the CHL : meh, not much difference.
Your bias might be showing.

As for goalies : goalies are weird, and cyclical. And it only takes 1 or 2 guys to create a 'boon' that seems substantial. 20 years ago everyone was from Quebec. 10 years ago everyone was from Finland. Right now the US is the dominant country.
And things are already shifting back by the looks of it. Past the 1998-born Swayman and Oettinger, there has been very little coming through the NCAA pipeline beyond that, and the 2 of the three best U25 goalies in the NHL this year (Wolf by a mile and Hofer) are all CHL trained. And the runaway best goalie prospect for the 2025 draft is a CHLer and the best goalie prospect this age Canada has produced since Fleury and Price.
Does this mean that NCAA goalies suddenly suck? No, of course not - it's just how it works. Things are cyclical, and all developmental paths are relatively equal when you pull back to the bigger picture over more time with larger sample sizes.
For what its worth, here are average market values and salaries for NCAA and CHL trained dmen (based on the Athletic's data)
CHL (44%) Average Salary $3.62m, Average Market Value $3.88m ($0.26m surplus)
NCAA (39%) Average Salary $3.50m, Average Market Value $3.96m ($0.46m surplus)
So CHL dmen are making more, but are they better? GMs seem to think they they are worth more.
Goalies - look at any list of prospects or U23 and you will find mostly guys from NCAA and Russia.
