I've had the English manga collecting dust on my shelf since I saw the set in a store a year or so ago. The art looked great at a glance. Big pages so you can take your time studying every detail. It should be excellent bedtime material. The Aria manga is similar in that sense, beautifully detailed, futuristic slice of life, and the new set (the Masterpiece) has the larger panels. It was out of circulation for a while but I think they have it for sale on Crunchyroll now. It's also the only English release of the manga that is actually complete. The anime both have Choro Club performing the soundtracks as well.
