Skating in hockey is much like running in football (soccer). Putting your head down and running as fast as you can doesn't make you a good runner.. it makes you a fast runner. However, being able to read through defenses, make darting runs and creating space for your teammates is arguably more important and harder to master than just sprinting.
The same could be said for this debate. Ennis is faster, yes, no one will argue that. But CoHo is a much smarter skater who makes plays with his skating.. he won't beat you in a foot race, he will however, skate in a manner which will create an opening for his teammates and allow them to make a play. This is also a reason why people tend to underrate Sam Reinhart, because he doesn't skate really ****ing fast like a Mackinnon, but is a more intelligent skater-- like a Zetterberg.
I just think we should be happy to have both, because they're both very good players, who are young and will be apart of this team for awhile-- if it came down to it, and we needed to move 1 of the 2, I would trade Ennis before Hodgson, and not think twice about it.
