Fanboys / Fangirls have been around for a long long time. Back in ancient times (aka 1980s) the common saying was "Nobody got fired for buying IBM."
Marketing works everywhere, even in that supposed bastion of logical thinking: IT. More than that, when someone is happy with the tools that they use, they will gladly try to make sure those tools are used by everyone.
This isn't really a workplace issue but rather one of how you approach brand recognition and customer loyalty in all walks of life. That said, I'll leave you with 3 fun facts:
Fun fact 1: One of the perks of being a decision maker is that you get to impose your world view on those around you.
Fun fact 2: Everyone who knows there is only ONE TRUE PATH is kidding themselves. The world is far grayer than that and is more than capable of supporting the mess.
Fun fact 3: "Best" is defined by the person using the word, is incredibly ambiguous, subject to change on a whim and few people can agree on what qualifies.
My advice: present your arguments for why you want to go a certain path and let the decision makers do the decision making. Then use your talents to make the best of it you can.
