After trying most makes over many years I've gone back to using D'Aquisto phosphor bronze uncoated strings. Gauges 11-40 on my carved top A5 style (equivalent to a D'Addario J74 set) and 10-34 on my flat top (similar to D'Addario J73 set). I prefer them to the D'Addarios as I find the quality control better (I've experienced many dud strings with D'Addario but never with D'Aquisto. They last well too and are equivalent in tone.
