In my own personal experience, these applications have almost never provided me with a more pleasant experience than eg a Qt application.
Plus I've had Slack's CSS mess up giving me a weird messed up UI. This has NEVER happened with an actually native application. I've also had Slack consume 4 gigs of RAM, which is ridiculous for something that is never the main thing I use my computer for.
Quicker time to market perhaps, but "reliable cross platform experience".. not in my opinion, at least, unless you mean that its reliably equally bad on all platforms ;-)
EDIT: Cross platform is easy when you don't need a platform-native look and feel, which web-as-native often doesn't do anyway (or not perfectly at least)
Most by number of apps? Consider all little enterprise things built in Java or whatever.
Most by time spent? Browsers, AAA games and file managers aren't web apps, surely?
Most by HN hype and VC funding?
