I wouldn't say that reapers being angels was a poor decision. Given that they're very powerful spirit beings on par with angels, it would only make sense to make them a type of angel, especially as the show plays off the idea of an "Angel of Death" myth. Also consider that in spirit/ghost form of humans that seeing a spirit being's true form would not beso dangerous to humans, so a reaper's true form and voice in Supernatural could very well be that bright light and ultra loud sonic sound like other angels but as they're generally smarter and more clever, they can easily shroud themselves better than their regulaar angel brothers. So it's not much of a stretch to make reapers another type of angels.
