Best meaning it has all of these features:

1. High quality scans.

2. Large scans so you can actually read what's on it.

3. Site with fast load times.

4. Accurate scanalations. i.e. the scans are faithful to Kishimoto's writing and you actually understand the scanlators' writing.

So far, the best sites I have are:
http://www.rootmanga.com/view.php?mn...=Kaede+Typhoon
AND
http://www.onemanga.com/Naruto/327/04/

Are there others?
