I like Ernie Balls and love the springy feel, the ease of a good vibrato and just the overall durability and tone. I've tried other brands which were ok but end up going back to Ernie Ball for some reason.
Same for me, Slinky 9s. They’re not expensive, they feel great, and I’ve never had one break on me in 12+ years.
Mainly because the EBs are relatively inexpensive and easy to get locally, and they remind me the most of the old Dean Markley strings with the sticker in the pack that you can't buy any longer.
