Not to get into the can of worms...but.
Generally speaking, in my experience, others may dismiss etc...(although I’m bob on right - had lots of rainy afternoons in a guitar shop to figure this out, 12 years worth...also, don’t start me on how weather changes them)
Alder/Rosewood - ‘Warmer’ sounding, lovely softer edge to the sound - notes ‘bloom’. Great for fingerstyle and such.
Ash/Maple - Punchy, snappy, very solid fundamental note - direct sounding. Great for Slap bass, Hard funky fingerstyle.
(edit - this is a generalisation, you can do any style you wish on any bass, whether it sounds ‘right’ or not is down to your ears/preference either way)
Someone will come along later and say something along the lines of “it makes no odds, it’s down to pickup choice, pickup placement, and tone is in the fingers...”
Yes they’re all contributing factors, but the way notes travel through a dense bit of ash, through the strings and into the pickups has some effect.
Anyhow, not getting into too much detail - literally choose one and play it. If it’s made of moon rock or Blackpool rock, as long as you’re enjoying it...it doesn’t matter.
I know with Sire it won’t be easy as some because they’re mainly available online. See if any local Basschatter can help?
I’ve never played one, although I wouldn’t mind a go...just to see what the fuss is about.
