I like deadbeef because it reminds me of the foobar2k days. Very simple interface but behind the context menu is hidden tagging, replaygain editing, a robust plugin system, and all the more advanced features I need to keep my collection well groomed.
I used both for years but always preferred weechat with the nicklist enabled and at the top, so that it didn’t break urls or selecting multi-line text. Although the nicklist feature is moot for huge irc channels the ui and user experience is overall better with weechat in my opinion.
