I think I've had an evolution, but I don't find these skyscrapers to be ugly at all.
The Édifice Marie-Guyart is a great Brutalist tower.

Is it a bit massive next to the national assembly? Sure, but its a powerful looking building, and since it is home to the bulk of the Quebec gvt, its aesthetic makes sense.
The Édifice d'Youville is a rather pleasant modern building that would be appreciated in anybody's downtown, I find.

The Delta is banal if anything, and is probably at its worst at ground level, but from a distance is looks like a respectable 20th century modern highrise.
The National Bank building is another quite ordinary modernist piece...

These modern towers indicate that Quebec, and Quebec's national capital is not a museum or set-piece city, but is a city that is in constant flux and evolution.
Or at least it was.
What I like about the Quebec skyline is the brash mix of modern (brutalist, especially) with the wide selection of older buildings. It's a completely unique skyline. There are no others anywhere in North America, or even the world.
