There were two "stock" squids, full blur and blurless... I chose full blur as it was my first rom I tried from stock stock, I upgraded with his fit a month, while mixing in trying everything else and removed 75% of the "blur" by the end.
Just like everyones phones oc and uv to different performance levels, same is true with rom reactions. I only speak for my own experiences and would never presume that what works best on mine is the best for someone else, apologies if that wasn't clear.
