Hi, I have extensive experience with RME and had the rme 400 , now UFX II. The drivers in RME is rock solid and you can record with low latencey (the is now way the Zoom will be that stable). If you record music, the RME is the way to go as it much better for that purpose (DsP with EQ, compressor, auto level of recording, high impedance input for guitar, etc.) , recording video sound the F8n will do well. Sound Devices will benefit from analog limiter, slightly less noise.
