These sort of Q? usually turn into a Who's Got What Brush fest?
But anyway, my only VULFIX brush is the Grovesnor '404' Badger/Boar mix.
It's a very cheap brush and gives a nice mix of Soft Bristles and Hair but with a decent backbone and not too floppy. It also holds a reasonable amount of water so is ok for lathering with both creams and soaps. The loft is not too high so it doesn't hold onto too much of the lather.
I have a Vulfix 377 and I'm not entirely certain I would recommend it at all as it is too floppy for my tastes and the tips aren't quite as soft as my Simpsons Chubby. They are certainly no longer "Best Value" brushes and there are IMHO better brushes out there at the price point than the 377. That said there is nothing actually wrong with the 377 and it is superbly built therefore I can't say it's a bad brush just not to my tastes. Also if you re-post in the brush forum you may get quicker responses.
There are lot of fine Vulfix brushes available. I think for us to better help you select a "good one" we should know a little about what you are looking for. Do you use soaps or creams? Perhaps both? Are you looking for a single brush to handle all your needs for a long time or do you plan getting a bunch of brushes? Big or small? Have you ever used a brush before? If so, what did you like or what did you not like about it? The more insight you can provide the better.
I'd hate to recommend you a sports car if you are looking for a pickup truck
