Native English speakers, which pronunciation features do you like the best?

[Etelfrido]

Native speakers don't choose their accent, although they can change it with time. Which pronunciation features do you wish you had natively due to them being prestigious, exotic or just because you think they sound good? It may be a rhotic R (for Brits, for example), Goose and Goat fronting etc.

I'd also like to know what you think of people who lack Happy Tensing and therefore use /ɪ/ instead of /i:/ in such cases (https://teflpedia.com/HappY_tensing) and those who lack the wine-whine merger, thus distinguishing /w/ from /ʍ/ (https://en.wikipedia.org/wiki/Pronun...%A8wh%E2%9F%A9). Do you think it'd be weird for a non-native speaker to have such pronunciations?

It'd also be interesting to know which accents are considered pleasant and why.
