I'm sure you're right that there are better and worse VAs, but I think that's just going to be the case in any and every system - including the private system. When my grandma was in private care, she would have literally been killed by the negligent staff if my dad hadn't intervened and gotten her care changed. Is that the case in every private hospital? - I'm sure it isn't - it's all about the individual hospital and management.
Re: um - no.
