Tools are just tools. Imagine scoffing at someone using a hammer, when in your less experienced opinion, they should be using NewHammer3.1.
Tools are means to an end. I much prefer working with people who care about the product and the business than what tools they used to build said product/business. I'm looking for "hey, you could save a lot of time by using tool Y", rather than "You people are idiots for even considering tool Z".
