Reply to Controller drop outs

I'm looking at getting a pioneer DDJ-SX but im concerned about potential drop outs with my laptop, it lives up to the specs for Serato DJ, using DPC latency checker i occasionally get a yellow spike into the 1000us range, i know someone who has a V7, if i use that for a while and get no drop outs, will this mean i should expect the same from the DDJ? or is each controller different?
