I like things that work. I think most technicians do, but as a web developer I have a very serious problem. My most effective environment for doing web development is the one that exists on my own personal box. It can also be a rather impractical place to develop because most of my customers (current and historic) are on rather customized server stacks. Typically, the host has customized the environment to their own specifications. It's not uncommon to find additional services like solr or maybe a memcache server in the mix.
