Echoing others: If at all possible, try before buying. I've owned Spector and played plenty of Stingrays.
Spector - Pros: crisp, articulate, refined modern "hi-fi" tone, great low B if you play 5'ers (partly due to 35"), more stable necks (multi-lam, graphite-reinforced).
Cons: Short upper horn and 35" scale means it doesn't balance quite as well standing up, longer reach to lowest fret(s). Less "aggressive" tone if that's what you're after (see below).
Stingray - Pros: That thick tone that others can approach, but not really duplicate. "One-trick pony", but it's quite a trick. Perfectly balanced IME.
Cons: Flip side of above, sometimes less tonally versatile (though the 2-pickup variants help). D and G strings can sometimes be weaker than lower strings. On 5'ers, the G string nut is cut a little too close, so it can tend to slip off the edge of the fingerboard depending on playing style IME. Less stable one-piece necks.
One wildcard to consider: G&L. The MFD pickup(s) can get more EBMM-like than a Spector, and more Spector-like than an EBMM. You may or may not find it to be a happy medium.
