H1 Stamping-First time in Extension

[H1 Visa/Stamp]

I am planning to go for my h1-B stamping sometime in Dec 2016 either to Canada or Mexico. I got my H1 in 2013, but I did not go for stamping since then. I got my extension in Sep2016 for 3 yrs. ..SO technically this will be my first time stamping. Should I go to my home country or Canada would work ?

Did anybody have any similar experiences. How are the stamping rate these days.. Please suggest

Thanks
