Nv2 vs Nstream on p2p links N and AC

I’m using nv2 on some p2p links and latency is unstable 1-4ms without any load. (N)
I heard that some people are using nstream for p2p links.

Can somebody say which is better for p2p in N and AC?

Hello, the ping time is normal
See here at this link i have made a linktest between two sxt’s on 802.11 and Nv2

See the result
