How come Toei at times can be so facking good (early/pre-time-skip One-Piece & DragonBall come to mind straight-away) and then can be so facking horrible other times (DragonBall Super, post-time-skip One-Piece format 1 chapter = 1 episode)?
I do have to say though Toei can really get the emotional things right-on. They really know how to do that well. Like this year alone I can think of the ending to the Episode of East-Blue special with a new version (epic nostalgic version) of the first One-Piece theme and then showing images of future members or allies.
One major reason would be how they work as a company. They're very good at knowing what trend to go for at the right time, at a time where very few studios are doing the same, thus allowing them to stand out. In the 70s, they got hold of the Go Nagai works that were pioneering some of the most popular sub-genres of today such as Cutie Honey, Mazinger Z and Devilman. In the 80s, they got the most popular battle Shonen of the time, Kinnikuman, Hokuto no Ken, Dragon Ball and Saint Seiya. The 90s had them boost the popularity of Mahou Shoujo with Sailor Moon and go further with the battle Shonen with One Piece and the Monster battle fad with Digimon, and in modern times they've rode on the nostalgia bandwagon with Super and Digimon Tri. However, this shows that they're more suited to be business men rather than animators.
The appeal of Toei was them grabbing a handful of good or decent shows and that despite taking many liberties in areas, this could allow them to stand out in unique ways. For instance, not being able to replicate Hokuto no Ken's art style allowed them to try their own which whilst not an equal, was still good at it's peak and became iconic. Saint Seiya's recycling of animation lead to it providing more build up for each character's attack with the pre-attack poses, etc. Music is also another main drawing point as I like the ost of most the shows they did, with OP's ost, HnK's ost and DB's Kikuchi score being amongst my favourite soundtracks of anime.
However, tying things together, Toei's flaw was not ageing well as a company. Sure, they had their faults even from the start, such as Osamu Tezuka abandoning their adaptations of his works and founding his own studio, but they still worked well with what they had beyond filler material. Their standing in the modern day is most likely due to how many more anime and studios there are than when they were founded and how they're covering many of the types of shows they once did. The Mecha and Mahou Shoujo genres are done by almost every studio and most battle Shonen have started to be picked up by studios like Bones, Madhouse, etc. Without being able to grab any new fish, Toei can only work with what they've got.
As for the decline of these series, it's likely a combination of the source material's decline and trying to keep up with the source material. One Piece has become more battle heavy than dialogue heavy from Marineford and onward than in the past, so a slow pace is probably what's keeping them from catching up to the manga. It's the opposite case with Super, in which the pacing is so the monthly manga can catch up with the anime.
Series that go on weekly for years without seasonal breaks would also put too much stress on their underpayed workers for them to keep to a high standard as well.
