Depends. As an "artist" who paints both traditional and digital you can make both look great. Both media have heir pros and cons and digital really isn't that much easier, nor objectively shittier. Sometimes it takes even more time than painting traditionally (also 3D animation isn't easy peasy either, you have to really learn it).

I think the problem is more that modern animes are produced fast and cheap and there isn't much time invested to make it good from the get go (see the enhanced BluRay releases, while the initial premier on TV is the crappy alpha version).

The industry has become pretty unforgiving (you either loose a lot of money or you win a lot) and studios try to cash in as best as possible, hence they produce way too much in shorter timeframes. Hell, most animators nowadays work themselves to death with 12+ hour workdays, yet earn almost nothing. They need to puke out these new episodes like a machine. I think there was recently an animator who died because of overworking.

I second this ^

As a digital and traditional artist, I can say digital can mimick the charm of traditional just as well. You just need to find that artist or studio who has the time, budget and love for their work to get something magical. You can find some fantastic looking anime every season, but you have to sort through hundreds of soulless  cash grabs first

I have seen Dragon Ball Super has changed the palette of colours they use for characters and they lately resemble real paint more because before the colours made the characters look dort of plastic, but still, I dont think it has to do with skills or even time but with the techonoly itself.
