Switching from ASP to JSP/PHP

Just wondering if any of you have any experience in switching from using ASP pages on SQL Server to using either JSP or PHP on Apache with PostgreSQL? Would it be better to just keep the ASP and use something like ChiliSoft on the Apache? Which is easier to learn JSP or ASP for someone with a basis in ASP?
