I've not directly compared the Oyaide to Isoclean or Wattgate. All are very fine products, and ultimately, things come down to a matter of personal preference. When we read of an end user stating that one product was "better", I always take that comment with a bottle of salt. Each product (substrate and plating) offers a different tonal quality, a different sonic perspective, and in some cases a different emphasis in the frequency range. Do you like a Stratocaster or a Les Paul Custom? A vintage Martin, or a Takamine? All are very good, but we will likely prefer one over another. Food for thought in our hobby.
