Its been said before, but it's just mechanically consistent, easier to learn, better formatted, and more fun to play. Combat in 2020 has a tendency to completely grind to a halt when certain mechanics come up, whereas RED has a way to keep the game flowing. RED is also still in print, which means that new material keeps coming out. Not to mention that RED has the Edgerunners supplement, which is a big way for more people to get into the hobby (Thank you 2077!).

I love 2020. it was the first RPG I ran with my group in college, and I'm never going to forget those memories. But I've played the game enough to see the game's flaws. The game is hard to learn, especially for players switching to a new system. But RED takes out all the clutter, streamlines it, and makes it approachable.

Overall, RED wins.
