Similar tone and similar theme (Dark tone, and demon slaying). Both have great animation and great soundtrack. They aren't the same, in fact they are quite different on other aspects (for example, the characters, the world setting and the art style). However there is a good chance you will enjoy them if you liked one of them since they have a similar vibe. Sorry the comparison is a bit vague but I don't want to spoil too much here.

Well they are practically the same in terms of theme and tropes. Ecchi,, High School Settings, and the MC has a massive Harem, and action based. However, unlike Strike the Blood, High School DxD has a much better world building, better characters in general, actually good plot, and the fan service is borderline Hentai. However I do think the actions in Strike the Blood are slightly better. If you enjoyed Strike the Blood I highly recommend watching out High School DxD. But I can't say so for the other way round. If you really liked High School DxD I can't say you will enjoy Strike the Blood for sure.

Well if you enjoyed Hyouka you probably enjoy Gosick as well, given they are both themed as mystery solving. But I do find the mystery in Gosick to be much more interesting and, well, they are actually mysteries, not just some high school bullshits. Do note that the two shows have some significantly different settings. Hyouka take part in the modern world while Gosick is in the early 19th century. Also, in terms of the storytelling, Gosick is more similar to Sherlock Holmes in some ways, while Hyouka is more similar to a typical high school romcom.
