no, it's not. while i can understand most of it written (and it took me more than 10 years being exposed to it via russian 2ch, so i learned a bit of words that made no sense to me before), i still struggle listening to it. and that's about common language spoken by bilingual ukrainians, if i read a literature piece written by monolingual native speakers from the western part of the country, it gets clear our languages aren't the same.
