I don't have any in-depth knowledge about them, just a recent interest. From what I've read there's not much difference, they're both considered good deals. Polish build quality is reputed to be a little bit better. The import safety lever can be different between the two with it a little bit larger and more prominent on the Romanian. That makes it either more useful or more intrusive depending on your point of view. A lot of people just remove them anyway to return them close to their original form.
