Here's a recent thread with a bunch of dynos we've posted, all from various tuners:
400 RWHP Club?
There's even one with no tune inching towards the 400 club.
In a nutshell, there is no "best tune" as every scenario (engine condition, location, octane, build configuration, etc) and one's needs are usually different.
I'm asking as in bang for your buck tune. I'm sure all these tunes are close from eachother but which would be the best value? That's my question.
