I had a persons interface before, all I can say is that I had way too much latency with instruments. I would recommend getting a motu m2 or m4 for this price range.
JustSayingI have this specific interface and I can say that there is little to no latency that I have experienced with it. I have definitely had latency in the past with much older interfaces from other companies, but fortunately that was not this case with this.
