You're both saying the same thing: fewer features = higher quality.
Swiss army knives are not as good at being screwdrivers as screwdrivers are.
In general: yes. But I’ve certainly had to use swathes of screwdrivers that are worse at being screwdrivers than my Swiss army knife is. Same I believe applies here: there’s a relation, but it’s nuanced. The same screwdriver is a better screwdriver when carried in a hand than in a toolbox full of other high-quality tools, but worse for everything else.
