If both driven properly with over 1000mw neither should have sibilance. HD800's brightness can come off as sibilant, but it's in it's character, and the 500's are an overall darker signature,, focusing most of it's energy in the upper mid-range. The HD800 is about the entire spectrum but the treble extension is one of the immediate takeaways. For the money they can be had for these days, the 500's are a fantastic buy.
