what are the best best 301 and 99 skins?

R-301 Ghostly Graveyard (rare) from the first Halloween event. It’s got a cool glow in the dark skeleton on and uses the default iron sights which are better than any of its legendaries 

R-99 Season 7 BP reactive skins (legendary)

It not only looks cool and emits energy when you down someone but it’s literally a pay to win skin as the iron sights are much clearer than the skins default model as it doesn’t obstruct the view of the enemy
