The difference between a mediocre harvest and a bountiful one usually comes down to uniform light distribution across your canopy. I have poured over the technical specs and aggregate buyer sentiment to compare these two options. In my view, balancing intensity with your specific space is the secret to success.

Choosing Between Them
I believe the AC Infinity IONBOARD S22 is the smartest choice for most people because its compact footprint fits perfectly into standard home setups. While the AC Infinity IONBOARD S44 is a powerhouse for those chasing maximum yields, the S22 offers the best balance of price and performance for a typical 2×2 space. My preference leans toward the S22 because it provides professional results without overwhelming your available room.
One thing you should keep in mind across this entire category is that AC Infinity requires a separate controller to unlock their full scheduling potential. This means you need to factor that extra piece of equipment into your budget before you start. Once you have that controller, the entire system becomes much more reliable and easier to manage over time.
