Excellent choice! I use a WR #6 for shooting and it does a good job. I also have a #4 and a #7, equally impressive. Basically a copy of Stanley Bedrock. In comparison to my Lie Nielsen 4 1/2, if I'm honest, I can't tell $200 worth of difference in performance other than maybe less edge retention. The cap iron and iron are very good, as well as the adjustments.
Out of the box, that's another story. You'll have to do a little prep with the WR whereas LN is ready to go.
Cosman has an excellent video on commissioning a WR plane. I highly recommend it.
Re: your original question, IMO you have to be very careful with offbrands. That said, there are some decent planes coming out of China (Quenshung aka WoodRiver) and one from India (can't remember name).
