I swapped basses for decades. Sooner or later, I never felt really happy with the tone, or it was just GAS. However, realizing that the desired tone I was striving for comes only from my playing skills and not from other, or more expensive basses, I simplified my life and am down today to two basses - a Fender Flea Jazz and a Blacktop Precision. Each covers anything I do, each feels well in my hands, looks nice and I love both. My interest is now more to “experiment” with different strings (brands, gauges, tuning, etc.) on my two basses. My GAS has moved to amps and cabs.
