As an owner of both the H90 and Strobostomp HD, I think it really comes down to interface rather than accuracy. Both of the tuners seem to measure pitch incredibly accurately (I mean, the H9/H90 is universally well known for its pitch tracking so….) the Peterson just has a massive interface meticulously designed to react and visualize even the smallest turn on your tuning peg. The H90 does just fine, but it’s no where near as visually responsive. I plan on keeping both on my board.
