Cymbals always sound like bubbling shit in mp3.
MP3 is not monolithic, and has changed drastically since it was released. You're going to get a pretty terrible experience with MP3 128kbps, whereas modern variable bit rate schemes can actually be quite decent. Personally I prefer to always go lossless, but for most people on most systems, the difference isn't noticeable. (Moreso the better the system gets, ofc)
To some extent certainly, though I think that e.g. the handling of short sharp transient remains somewhat of a fundamental problem of MP3 no matter how much bitrate and encoding brain power you throw at it, and was only really improved upon in the subsequent generation of codecs, i.e. like AAC, Vorbis or Opus.
