I have twice had 3 guitars that were the same model made from different wood combinations.

Some years ago, I simultaneously had 3 of the Martin "Women and Music" series.
-Rosewood/Sitka
-Maple/Sitka
-Mahogany/Mahogany
Same everything except wood.
(the tuners were different on the Mahogany model)

And another time I simultaneously had 3 Taylors of the 14, or GA, body style.
--Rosewood/Cedar
--Koa/Sitka
--Sapele/Sitka

And yes, the sound was (predictably) different with each guitar in the group, even though the builder and body shape/size was identical.

In both of these situations, it was more a curious game of acquisitions, rather than trying to find "my guitar".
I have a buddy who has 8 motorcycles in his garage (does a guy really need 3 Harleys?) and another who has a dozen sets of golf clubs...
my obsession was guitars.

To the OP, this can be a fun adventure.
But to quote you:
"Maybe I do need to just stop and be happy with what I've got..."
There is wisdom in your words.

But then, if a new guitar makes you smile, and you are current on the rent and utility bills, why not?
