According to Comic Natalie, Gin no Saji ~Silver Spoon has won the Manga Taisho award 2012. Manga Taisho is held annually and clerks of bookstores select the best title from relatively new series (less than nine volumes).
great slice of life - arakawa sensei is my goddess - may she continue to win awards forever!!!! aku no hana is genius as well - one of the most twisted and deep psycho-dramas ever (only problem is the scanlations are WAY too slow - i'm dying to see what happens next)!!! nice to see shuuzou oshimi getting some well-deserved recognition as well - yuutai nova by him is also amazing!
Well I can see why people would think Gin no Saji is boring as it's merely a farming slice-of-life coming-of-age story and there's no action, totally unlike FMA, and granted the first few chapters are kind of boring.
But seriously, as it went on, it started hitting it's stride and got really really funny. And it teaches you alot about the agriculture process and farm life in general, which I have a slight interest in. I felt like the manga really got good during the Pizza arc.
Although Silver Spoon's riding on Arakawa's previous success, it's a great SoL whose topic the mangaka has a personal connection with. It's certainly a 180 from FMA, however, so it's kind of ridiculous that some people are disappointed in it just because it's not an action series.
The plot idea by itself is not something that might interest you instantly, but the development is really cool. I can't say it deserved, though, because it's the only one I know in the list.
People have been very disappointed by Silver Spoon, because they expected another Fullmetal Alchemist. I think Arakawa-sensei took a great risk in writing Silver Spoon, but she has a great connection with this manga and is doing a pretty good job. Although it does start off a little slow, it really caught me when I was a few chapters in and it's main character will be able to do a lot for the series in the future. There's a lot of potential and I always like to remember people that FMA also started out as nothing special and just your average shounen, but got better over the time and ended as the best Shounen I've read so far.
There's a lot of room for improvement and knowing Arakawa, I'm sure she'll make use of it. :) As of now, I really like the series, let's see what'll happen with it.
