Both are asadora from NHK. The main character both came from Tokyo to the countryside. Both dramas also have the strong appeal of the culture and lifestyle of the countryside. Amachan was set up in Iwate, whereas Mare was set up in Noto. Both drama also offers a story of friendship and life journey. There are so many things that happened in life which does not always works in your favor, but the main characters are working towards their goals.
Personally, I prefer Mare compare to Amachan. I find the main character in Mare is more likable and mature. In addition, Mare story has more closure since it portrays her journey from childhood until adulthood and her character grown was shown very strongly compare to Aki.
However, Amachan also has some stronger strength. I find Amachan story is more realistic and not overdone with too much comedy (If you prefer realistic compared to fun watch, you might like Amachan more. In opposition, Mare has many weirds characters but also likable.), it also brings back memories of the old idol culture and nostalgia.
