PC vs Stadia Version
PC -
The PC version is an improved version of 21. I feel that the AI is better, the graphics are still very nice, and the features are pretty similar to the next gen version, despite being current gen. I have used some very nice sliders from Anth James, and have found each game to feel natural, organic, and just lots of fun. Playing the speed on slow, and on world class I find it to be a good challenge each game.
Stadia -
At first glance, I noticed while the resolution is good, it is not as clear as the PC version in motion, as it is streaming. If you do have a 4K supported PC/Monitor, it would look better. I just had issues with quality despite having good internet, and being connected to ethernet. The game was responsive, but just not as clear in motion.
The additions are nice. The animations are a bit smoother, and graphics are a tad better.
Is it worth it over the PC version? Not so sure. Once mods are released for turf, I honestly think the PC version is still a very good option. The Stadia version is nice, but just the occasional blurriness really brings the experience down. I do notice the gameplay improvements, but it is not as eye opening as I thought it would be.
Here are some pictures to compare.
