Here is a video comparing the two reactive load boxes.
The IR is OwnHammerIR's "OH 112 DVRB G65 SP2-00".
Three tones are compared: Crunch, Over Drive, Over Drive + DOD250.
IMO, CaptorX adds a little bit of compression and sounds cloudy.
Suhr feels more natural and clearer on high frequency, but it feels a little bit stiff when played.
