Bent Bulldog advice requested

You might want to take look at Peterson's line of bent bulldogs/Rhodesians. I always thought they had some of the best designs in a reasonable price rage. You can get most in either P-lip of Fishtail.

Big Ben pipes are made in The Netherlands and are carefully engineered in the Dutch way, I've heard. I don't own one. Having been to Amsterdam and elsewhere in The Netherlands, and having a Dutch brother-in-law, I would say the Dutch are careful workmen and craftsmen and have a love for doing products with precision. So I don't think you'll have a problem with that aspect of these pipes. Many Big Ben pipes have 9 mm filters. I generally don't smoke filter pipes, or I use adapters for Savenelli and other 6 mm filter pipes. But if you don't mind the 9 mm filters, or these pipes are offered without them (and I think Big Ben does make some non-filter pipes) all is well. As for one of the pipes being discounted or more discounted than the other, I wouldn't buy it for that reason unless it appeals to you more. I have found deeply discounted pipes that I really like to be great; you get the luxury of a better finish and more design features. But don't shop just for a discount unless you really like the item. I think Big Ben are established products of high quality. Just make sure you are getting what you want, filter or not, and in terms of visual appeal to you.

I have a Nording Viking bent bulldog that I purchased from pipesandcigars.com. It's certainly not your typical bulldog design, but I enjoy mine and it's always provided a great smoke. Ironically, it's what I was puffing on when I read the OP. I think Nordings are good quality pipes for the price, especially when they're on sale, like now.

I just noticed that the Royal Dutch Bowl Inner Dia. is 0.8"

I think that's a much better size for the squat bulldog to develop fuller flavor and thicker smoke by involving more tobacco area.
