Betamax vs Super Betamax Comparison Video Quality

In this video I compared video quality of Sony's Betamax format, Betamax vs Super Betamax during the format war with VHS. Betamax quality was the same as VHS 240 horizontal line. Sony at mid 80s introduced Super Betamax with 290 horizontal line that same as broadcast resolution at that time. Then Super Betamax should be slightly better quality than previous Betamax. In this video I compared this two format that in fact they players both were compatible with each other in playback. Please put your opinion on the comment. Was Super Betamax noticeably better that Betamax?
