I'm also wondering about the initial point, but ... Is there ever a best tool for _everyone_? I have only ever been convinced that something is the best tool for a job, when taking into a account a lot of context, exact requirements, available resources, etc. Otherwise you are almost always left with quite a large number of options that are equal for the information available and you can basically choose from by rolling dice. Regarding 2) I think it goes beyond comfort zone. I have seen plenty of completely chaotic, unmaintainable code bases due to the initial developer(s) starting the project without any prior experience of the technology. Of course many paths lead to chaos, but I would wary to start anything time critical in something too different to what I'm already quite comfortable in
