With regard to scouts, they're all going to hit a bit "light" in comparison to HC's. Hand Cannons are designed to hit like a truck but fire relatively slow to balance the high impact out. They're supposed to be aimed deliberately as opposed to spray and pray (at least the higher impact HC's follow this niche).
Similarly, the higher impact SR's will have a higher range, and lower RoF are to be more of a deliberate or precision weapon. The highest impact you can get on an SR at the moment is 61 (as opposed to an impact of 90+ that you can get with HC's). An impact of 61 will give you a 3 shot kill (pending all three shots are to the head) which isn't too bad considered the near sniper range that you get with higher impact scouts.
There's three different archetypes of SR's those being low impact/high RoF, mid impact/mid RoF, high impact/low RoF, and they're pretty much the same with regard to statistics within their respective groups.
The low impact/high RoF scouts (like the NL Shadow) aren't all that great and take a lot of rounds in order to kill (hence the high RoF). In PvP these will take 5 (apparently) rounds (or more) to kill which is why they're not all that great in comparison to other weapons in a different class.
The mid/mid SR's (Hung Jury is probably the most popular of these) are where the majority of SR users hang out at. These are the "jack of all trades" with regard to weapon use. They can be effective in PvP and PvE alike. In PvP, these will usually kill in 4-5 headshots, depending on your target's armor build. If you're using exotics in your primary, Mida most closely fits into this category and will kill in 4 HS.
The high impact/low RoF scouts (like Colovance's Duty) are generally good for PvP but are situational in PvE. SR's in this type are those that can three shot as stated above. With the right perk rolls and the appropriate situation you could potentially two shot with them (reactive reload, crowd control, bubble-buffs, etc).
Of course, your best bet is to find what best suits you. SR's are meant to be used from mid to long range. If you're not that type of player, then you probably shouldn't be using them. HC's are much more forgiving with hipfire than SR's are.
Since you're running GG, a single shot from Curse followed by a throwing knife will usually be enough to finish off your opponent. It's relatively easy to obtain, also, so that might be your best bet.
Edited for accuracy. I never really liked the high RoF SR's so I kinda guessed at it.

-
High RoF scouts kill in 5 headshots. Also, MIDA is kind of in its own archetype as it has less impact than medium impact scouts (37 compared to Hung Jury's 48) but also more RoF than medium RoF scouts (42 compared to Hung Jury's 37).

High road Soldier is the same archetype as mida. I can equip it if you want to see it.

High rof scouts are a 5 HS kill. ;)
