The problem is that not many of us has a working copy of LRP, therefore the PACT rule has not been rewritten to include the new parts.
The left-handed Nix supposedly has a larger than normal spread which causes it to ineffectively spray its rounds at anything outside of point-blank range. SYLPH is moderately more precise at longer range (which is still 75-150 metres, smaller than the Nix's maximum lock range) and has a much faster magazine reload rate which will allow you to empty it out sooner to be dropped.
It is still your choice though to use which ever part fits your play style.
