Prime is great. I've had mine for about 2 weeks but it looks like I've had it for months!
It's got a great shape and is awesome for anything! Stalls seem to be a little harder on it, but it may just be me. Lunar balance is on point, and it flips very well for lighthouse flips, j-sticks, anything where the ken flips. The tama also has a good bevel.
The paint is very sticky and durable, though during intense play it will chip a little (Like all paints). The cups are enlarged a lot which helps with lunars and lighthouses. It's got the biggest big cup I've ever seen!
Lunar balance overall should be really good because Sweets seems to have very consistent lunar balance with their newer models. Every single F3 I have has really good lunar balance, so these should be consistent as well. I can't confirm because I only have one Prime.
But overall the Primes are the best kendama for the price, in my opinion.
