I haven't heard of Cryorig AIO's being recalled due to faulty QC, thus I'd say go for them. Corsair have been suffering from pump noise and minor leaks. Quality aside, the Cryorig has a 38.5 mm thick radiator while the H100i v2 has a 30mm thick radaitor so with a thicker radiator overall, you're going to see lower fan noise and better heat dissipation.
Cryorig!
