I think traditional media can be lovely, and I'm always impressed by people who manage to make a traditional media webcomic, like Omekade, which is... just wow. 
The reason I don't personally, and haven't made a trad media comic since some old competition entries and anthology comics, is just that I'm too slow at it. I used to do it when I was younger; I'd carefully masking tape paper onto my dad's old rotring drawing board, I'd ink with fineliners or even sometimes nib pens, and colour or tone with copics... but then I became a professional and just couldn't keep up with both the speed of output needed and the need to guarantee consistent quality or be able to make changes in response to client feedback (and as much as we all would like clients to ask for feedback at the sketch stage... they often ask for HUGE changes once it's already inked and coloured
).
It's just so much work and stress making sure it's perpendicular, measuring all the gutters and trying to keep them parallel, worrying about spilling ink, or messing up a line, having to painstakingly paint or marker colour in every fill and then scanning it and touching it all up.... meanwhile I could make my panel borders in seconds in Clip Studio, fill even huge areas with a click or two and never have to worry about consistency of measurements because it's all set up, and be safe in the knowledge that most lines that go askew can be fixed with a flick of the ctrl+Z keys.
If I had to choose between an output of one traditional page a week, or my current schedule of two digital pages, digital just wins for me. Content is king and I have a lot of story to get through.
...But anyone who does manage to make a traditional comic week-in, week-out, big respect!
