Both. I could certainly be wrong about the guy, but his current ERA strikes me as a fluke. He has a K/9 of 5.17, and an xFIP of 4.04. He also wasn't highly thought of as a prospect coming into the year, getting little if any attention despite being in the worst farm system in baseball where you'd think he would standout. That sets off huge red flags for me and given his peripherals in the majors, I'm just not buying him. Granted, you could say similar things about Fiers though his current numbers and peripherals are superior to Quintana's. And as much as I like Fiers, I don't think I'd want to trade Greinke for another team's Fiers.
