British accents: Mr Baldrick vs Mr Blackadder

Dear Teachers

Sorry to bother you. I would like to know the two British accents in the following clip (in the first 15 secs)

Fight in the Dormitory - Blackadder - BBC - YouTube

One is Mr Baldrick (I believe, black gown), other is Mr Blackadder (I purple gown)

I can tell there is a difference, but I have no idea which regions their English accents belong to. As a Chinese, should I follow the accent of Mr Baldrick or Mr Blackadder, or none of both?

Please advise.

Regards

Anthony the learner

I wouldn't use Blackadder as a pronunciation guide- it's a comedy and uses funny voices quite a bit.
