I've got a Zoom R24 and tested this with the Kemper non reamping. sounds great to me, minimal latency .
In my normal setup the Zoom is only a DAW controller and use a Behringer FCA610 for SPDI and reamping. I record Always two tracks
1. mono dry guitar signal
2. SPDIF wet signal form the Kemper
This gives me the interaction with the wet sound plus the option to reamp if needed.
The Zoom has nice preamps and the FCA610 digital recording is quiet too, plus minimal latency too.
