Is a specialist really necessary for routine Jeep servicing?

I've been taking my Cherokee to a general garage for years because it's convenient and cheap, but I keep wondering whether a Jeep specialist would catch things they miss. The car runs fine but I've had a couple of niggles that never quite got resolved, and I'm starting to think it's because they don't see enough Jeeps to recognise the common issues. I want to learn more about what a specialist actually does differently before I switch, because I don't want to pay more for the same job with a fancier sign. Has anyone made the switch and found it genuinely worth it? Or is routine servicing routine servicing, regardless of who does it? I'd rather hear from people who've actually compared the two than guess at it.
