I use to play mostly on Dunlop, Gibson and Dadario strings for more than 10 years.
I decided to try HB strings just for fun.
Then I realized that:
1. It sounds like Dunlop nickel-plated strings
2. It stays in tune
3. It sounds normal approx. 3-5 weeks like Dunlop nickel-plated strings (I play guitar in average 4 hours per day. If you play less, it will sound ok last longer)
For me HB strings are not worse then Dunlop, Gibson or Dadario, but costs 2-3 times less.
I have found a way to get D-drop and C-drop strings for a really good price.
I buy HB EL-7 10-56 and HB 11-52 strings and compose from this sets D-drop (10-52) and C-drop (11-56) sets.
I have already used 6 sets of HB strings and did not have any problems.
