PCI is a more direct connection to the CPU (as is PCIe and Thunderbolt). USB is not directly tied to the CPU. It's what I've read but I could be wrong. The thing is that RME is able to build (in house) USB drivers as efficient and low latency as PCI and consort...
It depends also on the manufacturer and a lot of USB drivers are developed by the same companies (OEM) for a lot of audio brands. I think there is Thesycon developing for some.
RME are in-house;
Lynx, the same;
Motu, in-house I think;
Etc...
There are also manufactures adding "safety buffers", example choosing 128 buffer gives an RTL of 6ms. 64 buffer on another interface brand would yield 7ms of RTL...
A good reference for this stuff: https://www.gearslutz.com/board/music-co...-base.html
Nowadays, manufacturers claims "no latency" monitoring, as long as you use the direct monitoring of the interface/soundcards. However, in JK or in a DAW (when tracking with VST effects as an example), RTL is important.
Myself, I prefer 5-6 ms and can cope with 10ms but above this, it feels sluggish (on a keyboard with a software synth as an example) or delayed (if tracking guit/bass wit effects).
