Same. With the exception of Reddit (which I use a different client for anyway), I tend to just use the sites themselves.

Part of it is just not wanting those apps to invade the rest of my life. I know I can turn off notifications and things, but for some weird reason it helps me stay a bit more detached from social media when I'm forced to rely on the site.

The other part is privacy. I don't want the Facebook app on my phone. I don't want to have to worry about what permissions it wants and whether I've unchecked the right things. Using the web is easier for me in that respect.
