As climber07 says, which one is best for you really depends on your use and needs, even amongst point and shoot cameras. You have to decide what is important for you and choose a camera on that basis, whether your priorities are small size, telephoto zoom, wide angle, low light performance, ergonomic controls etc. etc.
Cameras from the major camera brands such as Canon, Nikon, Fuji etc will all be pretty much OK, it just depends which combination of features you need.
The cameras available in Hong Kong will be fundamentally no different from those available in Canada (although some of the newer models might reach HK a bit quicker) but the prices will be a bit lower. HK camera prices are roughly similar to the prices in the US.
