I mention vuetify as its faster to type than 'bootstrap-vue', but BSV is what I've used more. Used vuetify on one small prototype at the suggestion of some colleagues - some differences and nice aspects compared to BSV, but I default back to BSV for familiarity/speed/completeness. vuetify seemed to have some nicer defaults for accessibility compared to BSV, but it wasn't enough to make me switch (also, because... I'm not a huge MD fan either).
