This is an everlasting debate and I couldn't find a topic about this here. Which do you use PHP or ASP.net ? Why do you like it and Which are the reasons make you think your choice is better than other one ?
I'm a big PHP fan. I learned ASP years ago while I was studying web development but never got it into my self. But I self studied PHP and have loved it since the first day.
When you compare PHP with ASP (old version), PHP was better without question but now with ASP.net I really don't know.
