I wish I had a good answer, but what I do is point out why we are using what we are using. When we have a disagreement about this kind of thing my way usually wins because I'm the team lead, but I wish that weren't the deciding factor in most of our tech choices. I let that particular coworker use the MS stuff on small internal tools type projects, but when it comes to longer term stuff, or things that are more central to our company, I will push for the solution I think is best.
