The Epi T-bird classic-IV is an amazing instrument in feel, finish, sound, playability and everything in between. The Gibson USA p'ups in the T-Bird growl so much that they will frighten the neighbor's dog. The bridge keeps the bass from being a perfect 10 for me, but for $500 there is not a better bass on the planet. I play it more than my Lakland 55-60 or my MIA Jazz bass.
Also, My SX Ursa 2 Jazz is better than any Squier I've played and better than any MIM Fender I've ever played or owned. It's neck is excellent and the fretwork was very good. Electronics and p'ups were adequate and the hardware does the job. The poly finish is *very* good. For the $129 I pair for it from Rondo, it's the best bargain I've ever gotten. My next bass will be an SX MM/J. They are that good.
I think Epi's are better than Squiers in quality, construction, playability and sound, but again, YMMV.
Jeez, I own 4 Epi's: The T-Bird, an Epi EB-3 (Great sounding bass but significant neckdive is an issue), an Allen Woody (A short-scale. Good hollowbody sound with flats) and a Jack Casady (I'll take this bass to my grave - the p'up is killer and it sounds like a classic hollowbody should).
Go for the T-Bird - it's light years better than the other basses on the list. If you're interested in the Epi EB-3 send me a PM and we can work out a deal.
