No, I don't think so. Qui-Gon essentially held Obi-Wan back, at least in my opinion. THe obvious Jedi calmlness mixed with Qui-Gons casual and laid back training didn't really allow Obi-Wan to go all out. Plus, Ataru users require a lot of space, and as a result it makes it diffcult for two of them to attack one person at the same time. If you watch the movie you'll notice that Obi-Wan and Qui-Gon rarely both striked at the same time, and a couple of times they're sabers got tangled.
In my opinion, it took Qui-Gon's death and Obi-Wan's anger to unleash his true potential, in which we see Obi-Wan overpower and chop Maul's saber in half, in the process literally putting him on his ass.
I don't understand how someone who would get floored by a padawan, would beat Council Members with " considerable ease".
