I own both of what they tested. If you skip over all the pot shot commentary and go to the final conclusion I'd say it's fairly accurate.
Yes the Gibby does play deeper and smoother, the Eppi is brighter and more agressive, but either one can be eq'd to sound a lot like the other in a mix. And being able to buy three Eppi VPs for the price of one Gibson does make the the Eppi an exceptional value. I can agree with all that.
I don't find one any more noticeable than the other when it comes to feel when playing, both are great. As for neck dive when balanced in my lap, it's a non issue and no better or worse than a Jazz or P bass. Then there's the issue of the "non functional" tone knob, on a lot of my birds if I max the volume pot it minimizes any impact the tone knob has on the sound (I don't recall if my Eppi does that but it wouldn't surprise me) they should have backed the volume below 9 then messed with the tone knob. I also guess the little guy's ears are better than mine since he was able to clearly hear inconsistencies in the notes on the Eppi that I didn't hear.
So at the end of the day, they both took pot shots and displayed a clear bias against Thunderbirds but did arrive at a fairly logical and accurate conclusion.
