You are right about the OP thing, but sonic can be extremely good when hes in sticky situation, like if you double teamed, you can use side-b to hit both enemys, obviously is not at the same time so thats a little of disavantage. Yes, the his neutral-b and d-air are suicide moves, as long you dont get close to the edge of the platform or out of the platform, you'll be ok. But his side-b and down-b are the most accidentally suicide moves ever use. For example: You get blasted into the you try using your up-b but accidentally used your side- b or down-b and then die.
