@Natexxo I recently had the chance to play the Harley Benton side by side with a Squire VI, both strung with LaBella Flatwounds. IMO ...
...Build quality, and playability are equal.
The Squire sounds sounds better, not necessarily more or less low end, mid or treb, just a more pleasant, more vintage sound. Apologies if that's useless, I really struggle to describe sound. It's worth noting the comparison was made through a guitar amp (Fender Reverb) and I was in a "VI as a lead instrument" mindset. As a "bass" instrument through a bass amp the HB does a decent job.
More on the LaBellas, these strings really bring the HB and Squire to life, if that 60s tone is what you're after. However, the LaBellas are not a good fit for the HB, due to the shorter string length requirement due to the lack of vibrato system.
