For example with 4 Pierce main and 4 red-blast/3 blood moon in the sideboard I am curious how you play versus RUG postboard.
More important than that you need to get a realistic idea of the strenghts and weaknesses of sneak-attack. It seems that you overvalue it, which is strange if you really play it since January.
Don't know which decks you played before that sneak is the most consistant one you've ever played, but there are certain consistency issues in sneak attack. Usually high power has a tradeoff with consistency and Sneak attack is a good compromise on that spectrum, but there are certain draws (mull with little/no cantripping) where you lose to "yourself" or very little disruption.
Also your matchup evaluation that there are no real negative matchups preboard seems a little optimistic to me. Especially RUG Delver but also Miracle control, Reanimator, Dredge, Merfolk and Death and Taxes are negative pre-board imo.
