Specialist or generalist: Which route really pays off for mechanics long-term?

I've been turning wrenches for about eight years now, and I'm stuck on this big career call. On one side, diving deep into a single brand, like only working on Hondas, seems to bring in steady cash and builds a strong reputation. But then, staying broad lets you handle anything from rusty trucks to fancy imports, which means more job options. At my old place, we had a Chevy expert who made good money but got tired of the same engines day after day. I enjoy the challenge of learning new systems and not getting bored, but I worry about missing out on higher pay. Some shops really value that niche knowledge, while others want someone who can fix it all no matter what. So, what's your take? Is it better to master one thing or keep your skills wide open? I'd love to hear from others who've faced this choice!
