I'm not sure but traits have some adds to this.
If you look chart you can see Malice equal to Scope and Lynx but when it comes to hit things are changed.
not sure effect of traits but it seems adept and expert traits add to much % to calculation.
in my opinion list goes like Reaper>Shadow>Scope>Raven if we look at price Raven>Shadow>Reaper>Scope, Shadow and Reaper got Chameleon trait gives them +camo advantage against Scope.
at the beginning snipers not much needed (against low level enemy) so can wait about 4-5 days solve Skyriders quest enough money to call Reaper or Shadow and at that point you have daily income at min 9k +quests and weapon sale money at least 9, day you have them both in team good marksman with sneaking means deadly merc for me
