Not so sure Quintana is an Ace. Solid pitcher? Yes. Will he go out there and pitch a complete game shutout for you? No. He'll get you 6-7 strong innings consistently.
I think there is a pretty big gap between Ace and Solid Pitcher.
I can agree he doesn't always go deep. He's got 1 complete game in his career. But 84% of the time he pitches into the 6th, over half the time into the 7th. He's pitched 200 or more innings for 4 years straight. His ERA in those 4 years ranges between 3.20 & 3.51. Over the last few years, his WAR for pitchers has been 10th, 15th, 10th, & 30th. He's not Sale, Kershaw, or Kluber, but he's the next tier. Over that 4 year period, he's 7th overall in WAR for pitchers.
It is pretty safe to say he's an ace or near ace entering his prime and under control.
