I had done an analysis for 2018 and 2019. To be very brief (not attaching any sources at the moment):
In 2019, there's a good case for device being above s1mple, looking at their relative play-offs performance, performance in the biggest events, achievements (MVPs+EVPs), etc. s1mple was ahead of device in overall stats, as well as against Top5, Top10, and so on. Statistically, s1mple had beaten device in many categories in 2019, but not by a very big margin. device's achievements, and performance at the highest level, leads to a debate for 2019 Top2 spot. It was close.
In 2018 however, it's an entirely different story. Doesn't matter which stat you take, impact rating, consistency rating, ADR, KDR, Opening Kills, Multi-kills, Overall rating, ratings against TopX, literally whatever you wish, s1mple's numbers were the highest, not just for 2018, but in all of Tier1 CSGo history. Till date, they are all-time CSGo records, unbroken. That year, there was "no scope for any debate" (quoting the HLTV article). device did have 13 (MVPs+EVPs) compared to 10 (MVPs+EVPs) for s1mple, and that's the only one thing in device's favour.
Have a nice day :)
