I've had no issues playing flats over the past decade. I can get the tones I need with pedals/EQ just fine. Granted I'm not playing much hard stuff, but with my rock band if we do get heavy I've been fine.
For me as I've gotten older (36, so old....) I'm getting more simple with stuff. I have like just a few pedal sounds I use, mainly clean and just boost some eq on my bass as needed, then a tube overdrive sound, and then some effects for cover tunes (chorus, a synthy octave to emulate key bass) and that's about it. I care way more about my tone than anyone else does haha.
