That is the question.

I can see pros and cons to both.

Anticipating I will be getting one in a few months, wondering what all think about one v. the other.

I kind of like the doser one as it works pretty much the way I have grown up seeing in Cuban coffee shops.
On the other hand, I see that it will likely have coffee waste v. the non doser that drops exactly what you grind at that moment into your portafilter.
On the other hand, the non doser makes you stand there waiting patiently, holding the portafilter in your hand, as it grinds away.
