Wow old thread revived. I’ve been through over 100 other boost/od pedals since I lasted posted in this thread lol
As of now it’s by far an original Klon Centaur, but my next favorites and less pricy options would be either a vintage TC Electronic 1140 or Furman PQ-3 (they’re rack units not pedals, but sound incredible)
The Coppersound Broadway is cool if you want a more raunchy, bluesy kinda lead tone
Those are the only 4 boosts I’ve kept. Everything else I’ve had lost to at least one of those 4 to my ears in the AB comparisons
Not sure what to suggest if any of those are out of budget or impractical due to being rack units/not pedals, but it seems like the other suggestions here are pretty solid for more affordable options
