A few years ago I researched the market for a replacement LNB. I needed a low noise floor and high gain. I bought a Black Ultra and I was really pleased with the signal.
Today, 28/3/19 I bought a professional satellite alignment tool. The dish was quite a long way out - I gained 6dBuV to 51dBuV. I then swapped back to the old LNB which must be 30 years old, and gained another 7dBuV. I seem to remember that the bandwidth of the old lnb is less, so it can't get some of the channels like 4/7. But it might mean that BBC is better in the coming month - can't get HD currently.
