I own modulus, spector, ibanez and esp basses. I play the esp basses live. Like most companies quality is hit and miss with foreign made basses. I would NOT say the ibanez quality is anymore greater then the esp basses. I will say my ibanez 5 string's neck warped and the preamp wasn't the most usable. does that mean the company makes bad basses? no... I've heard and played some nicer sounding ibanez basses so I know its not all their basses..
what Im trying to say is... for the most part foreign made "budget" basses will be hit and miss. Unless you're paying for something in the $1000+ range I would worry more about bass that feels comfortable and gets you the tone you want. I use the Esp basses 1)because they sound just as good as the spectors through my gk+mesa rig for the tone I want and 2) I dont worry as much about the basses getting damaged or stolen because they run about 3-400$ 3) Its a cosmetic thing.
I did a show with the band Hemlock a while back and thats the same bass their singer uses. Sounded fine and he's had it for years.
