white is a funny beast, there's nothing that's a massive guaranteed advantage , I put that down to the pigment being titanium dioxide sounds expensive (as crazy as it sounds one thing the bridging coat will do is make the wall less thirsty= less paint used on the top/colour coats) I wouldn't worry about opacity. The tikkurila mentioned above is excellent in situation of dual natural lighting/ particularly awful ceiling surfaces, it somehow works on the texture it gives thus if used as a mist on filler it will horrendously flash the texture through especially if using a finish specific paint (f&b)
