In my team the PG is more important than the SG. He scores more with the same JS/JR, at a better % and is a better defender. The PG is actually a better passer but the SG has more assist per game.
My PG also makes about 2.5 times as much as my SG since I want to have a very good playmaker to help my offensive flow.
This makes it very hard to compare and say whether he's actually more important. I guess you're looking for 2 similar teams except 1 has a great PG with 200k salary and SG with 70k salary and the other team has the SG with 200k salary and PG with 70k salary.
The caveats are all true, it will depend on the rest of the team and what type of offense you want to play. So In think a simple yes...wouldn't be fair to the question.
