J2EE generally requires high-power -- read expensive -- servers and it is not routinely implemented in most shared or dedicated hosting environments. It is, however, a viable alternative to either ASP.NET or LAMP implementations.
ANALYSIS:
ASP and LAMP have a long shared history of competition as the foremost of the Web development suites, dating back to the early 2000s. Their fans are legion and frequently at odds with each other. Any gathering of programmers and coders is reminiscent of the old Miller Lite TV commercials, where one side shouts "Tastes great!" and the other responds with "Less filling!" Just as in the commercials, one side is not really superior to the other, although even that statement is likely to spark a heated debate amongst the "true believers."
As a general rule, ASP.NET is the choice for any Windows or Microsoft-savvy coder. The development tools are similar to every other MS application and the learning curve is relatively short. Drag and drop WYSIWYG and a plethora of computer languages make it the obvious choice, especially if money is not an option.
