I don't think this is necessarily a cold vs warm water thing, and I don't think it's a matter of where you got certified. However, people that ONLY dive following guides have a different set of skills to be concerned about than people navigating for themselves. Let's take two rich couples that both retired 6 months ago and got certified at the same time by the same instructor in Cancun. They then moved, one couple moved to Bonaire, the other to Roatan. In Bonaire, they do 6 dives a week, they do all of their own navigation. In Roatan, they do 6 dives a week, but they follow the guide every time. Who will have better nav skills? Who will have better planning skills? It's likely that in 10 years they'll be equally competent, but I think that the learning curves vary.
As for cold vs warm water divers, I think there is some merit to diving in cold water as there is added complexity. If you get used to the increased complexity of the cold, the warm water will be simpler and safer. Another thing is that it takes more dedication to dive in cold water with low viz than it does to dive in perfect, tropical paradises. The kinds of divers that are most likely to work on perfecting their skills are the kind of people that would dive locally, despite bad conditions, to ensure their skills were perfected. I know that last sentence sounds circular, but it's really not.
