I haven't heard of most of those. However, I am restricted in what I can load on the servers at work.
I'm doing more PHP recently, but that's mainly because of the work I'm doing here with MediaWiki and phpBB.
.Net can be rapid and helpful, but I've never liked the database handling. Sometimes it's blissfullly easy and other times it fights you all the way. I went back to one of my web apps recently and discovered that the SQL server hosting the database had been removed.
I created a new database with a better structure on another server, but the XSDs, Table Adaptors and all the other junk where such a pain to adjust that I ended up writing a couple of functions to let me fire raw SQL strings at the DB and things are much simpler now.
