It's close, they are my two favorite decades of gaming. I'm going to give it the 2010s because my Top 3 games are all from the 2010s, for one.
3. Super Mario Galaxy 2. 2. Super Mario Odyssey 1. Stardew Valley
I'd also take PS4 over PS3, 3DS over DS, The early years of Switch over the early years of Wii, and so on.
And despite some of the scummy online practices that really got big in the 2010s and still exist, I like added online features like playtime tracking, faster syncing achievement systems than Xbox 360 and PS3, and so on.
It's a really close call.
