I owned both a 2015 Music Man Stingray Classic 4 & a 2008 Fender American Standard jazz bass.
I bought the Ray first & then secondly the Jazz.
The Ray was $1200 used & the Jazz was $750 used.
Aesthetically, I feel the Jazz is gorgeous & the Ray is " primitive " looking.
They both felt & played very well to me. I especially loved the Ray's trussrod adjustment wheel.
The Jazz is a hair over 9# & I'd guess the Ray was 10.5 - 11#.
Both necks felt great, but, the Ray neck felt particularly " rubbery " or soft to me with quite a bit of give to it.
The Ray is probably technically more gorgeous with it's bird's-eye maple neck & natural ash body, but, my Blizzard Pearl Jazz is no slouch.
Sound wise, I love my Jazz bass & it's versatility. The Ray I felt was lacking in the tone department. Yes, it's a single pickup bass, but, so is my Blizzard Pearl Precision bass with flats & between hand placement & the tone knob, my Precision is plenty versatile.
I ultimately got rid of the Stingray, though I may consider buying another someday.
Good luck with your bass search!
**** Another thing is I never could achieve withthe Ray was ultra low action. The strings wouldn't adjust as low to the frets as I wanted with the bridge saddles. I've never had a bass I couldn't adjust to 4/64" - 3/64" @ the 12th fret, or lower if wanted, besides this one.
