I guess I've usually hovered between Elites, EB's and Rotosounds depending on what deals might be going though have tried many others over the years.
Previously, my Tune 6-string had a set of Jackson's. I bought 3 sets on a trip to the US - $25 a set. Which was nice!
I've also used Trace Elliot strings, ranging from their BLX series to their regular sets for both electric and acoustic bass.
I had a brief deal with Gibson a few years ago so was able to try their bass strings for a while. Actually not bad but I probably wouldn't have considered them above the usual suspects otherwise. Ultimately, it's trial and error til you find what feels right for YOU.
Best strings for me would be anything that was permanently 2 weeks old, i.e., just played in enough to take 'newness' off but still have a brightness to them to the end!
