I've been using Elixir strings for years now. I like the "feel" and sound of new set of strings, but I am too lazy to change a set. So coated strings are ideal - they keep that new set sound definition for longer than regular strings.
HB coated strings feel good and they sound good. I never made a direct comparison between a new set of Elixir and HBs, I go by the "gut" feeling, and that one is good, recordings sound good.
If you are a recording artist and do a lot of studio work, then you probably have your strings game already in order. If you are like me, ie. not a professional, these strings are ideal for practicing and recording as well. Ideal for that guitar that you forgot you have, but still like to take it out of the case and play it once in a while.
Given the price and performance it's now a no-brainer for me - I can get 3 sets of these strings, instead of 1 set of Elixir strings. Sound and durability so far, seems to be 80%-90% of what I've seen with Elixirs.
