I like both, for different reasons, and I've done comics both ways.
Grassblades is done 100% digitally (unless one counts the storyboards, which are scribbled on paper) because it's faster that way, and I do have a schedule to keep up with. Also, I'm less likely to get all nervous and get neck-pains when I ink digitally - I get all tense when I ink traditionally, afraid of messing up, which can give me serious aches in my back and my neck.
Also, I have a cintiq, which means the digital inking feels closer to traditional for me.
But my very first longer-format comic that actually finished - called Fathoms of the Sky - was inked traditionally. The only bit of it done digitally were the speechbubbles, because oh my me do I ever have crappy handwriting.
It's inked almost entirely with a Pilot Pocket Brush pen, because since I
do get so tense about inking traditionally, I tend to get very stiff when inking with stuff like Staedtler pens. The brush pen helps soften up my line and make it less mechanical.
These days, I don't ink comics traditionally, but I do ink illustrations that way - either with a brush pen or with an actual brush - and I do colour illustrations with watercolour (well, let's be honest, it's watercolour+whatever else I had lying around. Acrylics, coloured ink, coloured pencils, tea... whatever).
Both have their advantages.
