Near-strictly a desktop reader. At least half the comics I read are vertical scroll (my own comic is vertical scroll!), and I greatly prefer them on desktop. I feel claustrophobic when I try to read on my phone.
That being said... Tapas as a place looks a lot better on the phone than it does on desktop. The desktop site also gives me a very annoying glitch (I think it's a glitch) that sends me to an older episode when I click on "new episode for a series you're subbed" notification. This, unfortunately, leads me to not read much on Tapas. I do most of my reading elsewhere, still on desktop.
