Re: "Errr, remind me, which was the best out of those?"
Wrong, Video 2000 was the best.
It used metal oxide tapes, you could flip them over like a compact cassette. It had a proper still frame using both video fields (Beta and VHS could only show one).
Noise reduction, auto tracking, data track on the tape (subtitles etc), fast forwarding without lots of noise on screen, half speed mode (on later model) which increased record time to 8 hours per size, 16 hours using both sides of the tape.
VHS and beta are just shockingly crap compared to Video 2000. But there was a problem on early machines, a lack of pre-recorded titles and its high price too.
