Here's another vote for the Yamaha stuff. You absolutely get what you pay for. But my suggestion is: if you're able to, buy the cymbal stands, snare stand, and hihat separately and used, and spend good money on the kick pedal you want.As others have said, either will deliver as promised but now I'm just considering which hardware would have the best long term utility, versatility and possible resale.
I don't really agree with hardware packs including a kick pedal as those tend to be more up to preference, and while it's a perfectly fine light duty or spare pedal, what comes in the Yamaha pack is pretty basic and might not be your cup of tea.
As for drawbacks, the main one with the Yamaha stuff is that the tilters are geared, but for cymbals I don't think that is enough to be a dealbreaker. Meanwhile the snare stand tilter is not geared, which to me is more important anyway.
