Accelerated encode in particular is very likely to give inferior quality and a more limited range of encoding options, and also introduce a situation where those factors change from machine to machine (say, based on which codecs and options your particular GPU supports). Of course, if speed and resource consumption are the key factors then it can definitely make sense to use them, but probably not as a default.
