The park tools one is amazing! (caviat; always cleaned the chain manually before, so no experience of other brands)
It’s super easy to use, takes all of 30 seconds to get the chain so clean it looks new.
Only trouble is the degreaser for it is expensive and I’ve yet to find a substitute that works as well. I’ve just replaced the brushes that were about a year old; this needed doing, the bristles bend so after a while its not as effective
