CLYW is far from being the ‘better’ company out there. CLYW does sell a lot, but there’s not that much variety in their current products. Which is, by the way, the reason I’m not getting why people are collecting several Peaks instead of having one or two Peaks and a lot of other good yoyos. But that is a completely different matter that shall not be discussed at this particular moment (this means please don’t bring up a debate on this).
YoYoFactory or YoYoJam are in my opinion the only two companies out there which can fight for the title. Both of them have models fitting for the new thrower or the advanced player (World Champion as well). They are also known to have customer service which holds a required level.
There are differences in these companies though. YoYoJam’s line of yoyos is almost entirely based on signature models designed for their team members.
While YoYoFactory does make beginner models, they are known for their precise machined metal yoyos. And while YoYoJam is not known for their metal yoyos (they do have them and they play good), they are known for their metal-rimmed yoyos. They have and endless line of nice playing metal-rimmed yoyos which play exceptionally well for the price. And who hasn’t owned a 14 dollar YoYoJam plastic?
So the decision is pretty tough between these two companies. But in the end, I will say that they fill each other out perfectly. YoYoJam’s line of metal-rimmed yoyos can fill out the void in any company’s line. And YoYoFactory’s great extensive line of well playing metals can fill out the holes, YoYoJam’s two full-metal models can’t.
Addment: No other company can offer as much as these two.
