They’re both the same “type” of switch in JWK’s offerings—a medium tactile consisting of their sharper tactile stem with pretravel and a lighter leaf to reduce/round out the tactility—but the FFFF tactiles are marketed as having a nylon top (rather than the standard PC-top the Taro Balls are marketed as having).
In practice the difference in sound between them seems minimal at best (which could just have to do with the specific switches I have), so I think that if you like the sound & feel of the FFFF tactiles you’ll probably also like the sound & feel of the Taro Balls.
Another option in this type would be the Durock Medium Tactile, which features a clear housing and purple stem if you want something a little LED-friendlier (not sure if that matters for your build).
