As I've gotten older, I have grown to understand that while a lot of these films are popular for good reason (and are extremely good!) some of the best films, objectively to me, are some of the 'quietier' ones.
I'd say that Up On Poppy Hill is probably my partner and I's favorite Ghibli film. It's 'small' and 'quiet' in that the scope is a single town, and there's nothing super fantastical about it. Every time I watch it I see and hear something new. This is definitely Goro's best film as a director at Ghibli.
The film that hit me the hardest though is The Wind Rises. If you are a married man this is a film that will absolutely effect you emotionally. There are some films that are targeted as extremely specific audiences and this is one of those. I think everyone can enjoy it, but there's a handful of scenes that are so specific that I connected with so directly that I could feel every moment that Miyazaki was trying to convey at that exact time.
There's another film that is definitely more biased to adults, that is Only Yesterday. It's probably the slowest paced film that Ghibli has made, however it's one that's stuck with me so thoroughly. Especially the final few scenes, which only when they're over do you realize was something like 15-20 minutes with maybe a handful of dialogue lines. This is also another non-Miyazaki film that is extremely good.
