yeah it does matter.
see it's the mindset of your visitors.
no one here based on U.S. claimed that they saw something like this and that on .ph domains?
see
while we see local products and are interested on it, but the interests somewhat affected if I tell you it can be found on .ph
also it does well on your google search results.
if you have .ph it ranks well most of the time on google.com.ph and visitors here uses google.com.ph not .com of google.
just do a hand-reg of the .com
