I know that vim-matchup has not many stars on github but it is quite new. IMHO, it represents a significant improvement of matchit and matchparen and therefore I can highly recommend it.
nvim-completion-manager is nvim-only, so it doesn't fit here. :]
I have a love/hate relationship with vim-sleuth, because it I often got false positives in the past. I'll add it anyway. People should try for theirselves.
Huh, didn't know about vim-matchup. Looks good! Will add.
vim-sleuth: I guess you mean by false positives that vim-sleuth did not properly detect the correct settings for 'shiftwidth' and 'expandtab'. Tim Pope mentions in the README.md that the plugin is not yet battle proof. Therefore, I understand your hesitation. Maybe one could point user to the project https://github.com/editorconfig/editorconfig-vim and https://github.com/sgur/vim-editorconfig. This is also advertised by the new book Modern Vim by Drew Neil.
I am quite happy with vim-matchup and I hope others can see its value as well.
