Normally you want the higher impact snipers. These include 1000 yard stare. Y-90 longbow synthesis. Or the LDR 5001 those are the best high impact snipers in my opinion. Overall, there are 4 Scopes that you want Short gaze Ambush Longview slr10 And the one that looks like the dreadnaught. (sorry i dont know the actual name) Personal favorite is shortgaze but their all viable scopes. The main perks you want on a sniper for crucible are Hidden hand Last resort Grenadier is nice for warlocks Army of one is good Life support can help you get out of bad situations with the heal (milligan, performance bonus, and rescue mag are nice because they help with conserving special ammo and I'm not the best sniper so they help me) In the middle column the best perks are Quickdraw Snapshot Injection mold (anything for range because range = aim assist) There are many other perks but those are just what I Think are most "competitive" and they are also my favorite (P.S. my grammar is normally not this bad. Half the time I used periods instead of commas. Anyways I hopes that this helps you and best of luck sniping out there in the crucible. Again these are only my opinions there are a ton of YouTube videos on this stuff if you're interested.
