All of the numbers are in Schumacher's favour with the exception of percentage of pole position starts. Even then, Schumacher won a higher percentage of races, despite starting from the front less than Senna did.
The arguments for Senna are largely the intangible ones. Strength of opposition for example. The problem with intangibles is that they are very subjective. Senna competed against Prost, Piquet and Mansell, champions all. The question is, how do these guys compare to Hill, Hakkinen, Villeneuve and Alonso? I'd say it's a slight edge to Senna because of Prost but I think Hakkinen and Alonso compare to Piquet and Mansell favourably.
Strength of machinery? They both had the best at their disposal and both won with cars that weren't the best. I don't think this one either detracts or enhances the arguemnt for either driver.
Teammates? Again, the Prost factor gives this one to Senna. Schumacher raced against Piquet, but only briefly and it was Piquet's last season.
I don't feel that Senna having the edge in terms of who he competed with and against outweighs Schumacher's strike rate. Schumacher won with metronomic consistency that made his competitors look worse than they actually were, rather than them making him look better than he was.
