Mine is the yoyojam unleashed because it loops fast and doesn’t break strings quickly.
loop 1080 I can loop much longer than an unleashed with this
I’ve tried the fireball, 808, modded hyper raiders, and unleashed. Unleashed gets my vote but the hyper raiders are close behind. 
try the loop 1080s
I like the Unleahed and the 1080 about equally.
I have a pair of loop 900s but I don’t know what differnce is from the 1080s
The Raider EX.
Straight from YYE: The adjustment mechanism was improved and moved from being off centered to the very center of the yo-yo halve. The plastic spacers were resized and slightly re-designed and the weight and shape were very slightly altered.
I think they moved the adjustment mechanism to the center because the Loop 900 didn’t feel well balanced. I may be wrong though.
