What Linux distro is best for development

Huh?

You need to state exactly where the problem is before you can receive solutions.

Once again, there is very little difference between the distributions. They all pull from the same pool of kernel, utilities and applications. They differ in philosophy and what they include (or exclude), and not much else.

Pick an "easy to install-easy to use" distribution, and chances are it won't be a good choice for program development, because it's aimed at a user base that wants to use programs, not make them.

SInce you've gone through most of the distributions, an obvious question is why you keep changing them. You've clearly jumped over some obvious choices for "development", yet you keep searching. You are less likely to find the development tools on a glossy distribution.

But, it doesn't really matter. Because if something isn't included, you can install it, either via a package set up for the distribution or via source code. A glossy distribution doesn't leave off the development tools because they won't work, they leave them off because their target market isn't interested in them. You can add them yourself.

Of course, if you want glossy, that may not be the best environment for program development, but that's another issue.
