Hana wa Saku, Shura no Gotoku Episode 10 Discussion

I understand what you mean in the sense that the statement you quoted from that character did feel slightly - and could be easily interpreted as, condescending and derogatory, but I don't think that it was intended to be. I think that what the character in question was trying to get at and demonstrate is that there are multiple different distinct styles of reading and oral presentation intended for different audiences. It's similar to how anime, cinema, manga/comics, and other forms of media cater to different demographic audiences. Hana's style is very lively and animated in a way that is usually interpreted as for children because she excelled in reading as part of her children's storytime sessions - that one-girl show she put on for the kids in her local community on her home island.

That style is one which is likely considered just the right fit for children and younger people (alternatively could also be appreciated by autistics and the developmentally/emotionally stunted who prefer emotions to be upfront and worn on the sleeve, and more exaggerated and caricature-esque performances), but could be considered too pat, showy, cheesy, and over the top. As opposed to a quieter and less boisterous performance which could be seen as possessing more depth and nuance, and more appropriate for an older teen and/or adult audience. It may also be more in line with the prevailing style sought at these regional and national-level competitions by their judges.

Presumably the older students who have been in their respective schools' clubs longer and have some past and involvement with the large competitions are more informed than both the character of Hana and us in the audience at this point as to what they're looking for or if there is one closely followed and strict enough standard observed and enforced with little room for creative deviation, but that point might be further shown and elaborated upon later on.
