Grind machine vs hubstack( afterglow)

How well do these play and which is better?

Take it you’re choosing for the hubstacks

Would take the magicyoyo n9/T9/T10 over either of them.

Otherwise the Hubstack is a better shape but too light and the grind machine is an outdated shape with high walls. Would probly take the hubstack personally.

Never used grind machine
I have hubstack afterglow
it is an awesome yo for its price
but I tend to have to keep tightening the axle
it causes myn to vibe n slow down
other than that
It is a good throw

Ok. Thanks

How does the n9 play. And whats the spin time
