The BBC is a pretty independent body, and criticizes the government often. RT is a propaganda arm of the government and is under its direct control, as all mass media in Russia now (with few exceptions).
The BBC is quite balanced, I watch Russia today and find it similar in tone to most western outlets, both state owned and private ... screeching on about terrorism. Repetitive, mundane. They’re all quite openly propagandistic from my point of view.
