JHCCoffee alongside the faster flow rate, the Hario Switch has the benefit of also doubling up as a standard v60 if you don’t already have one. The glass construction is also more premium feeling at the expense of heat retention.
Clever has a slower draw down and so if you were to use it as a standard dripper it tends produce more body in comparison due to the controlled flow. It also uses the standard flat bottom filters which are cheaper to buy and more commonly stocked in supermarkets though, a big bonus especially now as @MWJB says Ocado suddenly stopped selling v60 papers.
