You need to find the sweet spot between availability and performance.
Availability: This might not be an issue for you depending on your local supply situation. However I would concentrate on those brands/models that have a proven availability and supply certainty. No good developing the perfect load only to find components aren't available when you need them. Many competitive shooters in my country were left high and dry for over two years due to a shortage of their chosen primers.
Performance: My experience is that you need to see what works best in YOUR gun with YOUR choice of bullet and load. The individual differences between guns of even the same make and model make theory dubious. Empirical testing is the only real way to find out. Make a whole series of small test batches using different brands and see what gives the best result. Tedious, but at the end of the process you'll have a load that you can rely on. Strangely enough, knowing that your ammo is going to give a particular accuracy, gives you the confidence to raise your own performance.
