Flights to PDL

Hello...we are planning to visit Sao Miguel in September for 10 days, , flying from Nova Scotia, Canada. Our plan was to fly from Toronto or Montreal with Azores Airlines. However, we are having second thoughts after reading so many bad reviews on that airline. And, we noticed that AzoresGetaways.com uses United Airlines via Newark, NJ (more expensive). Is Azores Airlines a good option...or do we rethink our vacation? Thanks for any suggestions...:)
