I don't know about -best- but I know I enjoyed it a lot both back in the day and recently.  I ended up buying the complete collection on DVD a few years back when HMV was still a thing in Canada.

If there was one thing Capcom got right: they got the Beast Wars and ReBoot cast voicing their characters. Seriously, Scott McNeil as Dr. Wily and Protoman is near impossible to top. By the way, I can also impersonate Cut Man, Bright Man, Toad Man, and Pharaoh Man.
