USB audio interfaces are the worst for latency. You can't listen to your guitar (bass, vocal, etc) through the DAW while recording, while playing back pre-recorded tracks and expect them to be in time. A/D conversion takes a couple of milliseconds, USB transmission to the computer takes a few milliseconds, passing thru the DAW takes a couple of milliseconds, and then going back thru USB transmission to get back to the interface for D/A (so you can hear it through the headphone outs, or other monitoring outs) takes another few milliseconds. It all adds up. Analog mixers/tape machines never had this problem after 'sel-sync' was invented. Yay digital...
I own a Focusrite 18i8. Focusrite interfaces include a simple hardware digital mixer built into them for the exact purpose of allowing direct monitoring of incoming signals without the round-trip thru the DAW, including the ability to mix live signals from the inputs with output from the DAW, and feed that mix to monitoring outputs. This is what you're looking for.
Spend some time looking at this (access is installed as part of the driver software package) and you will come to realize its power.
Good luck.
