As a Disneyland fan, I love the comfy old 1910 “Main Street” look. My home town has a town hall that would look right at home in Disneyland.
I’m also fond of 1960s – I don’t know the name – cantilever balconies and stuff. You know the house in the movie “North by Northwest”? That look. (Google says it is “modernist.”)
I adore the UCSD library, as another example.

Now everywhere’s so open, there’s no place safe to dress.”)

Roman classical, and Palladian styles are also pretty.
I’d never hear of brutalism before, but the images that pop up under Google do not make me happy. I’ll have to vote against that style.
ETA: Also, I love “Churrigaresque” style – not least because it’s such a fun word! Based on the church in Churrigara, Mexico. (I’m probably spelling that wrong.)
