I use two masks. One for excursion diving and one for the pool.
The first one is a Cressi Matrix that I bought in 2007. Well preserved it's like new. Only the strap had to be replaced. To avoid yellowishing I cover it with liquid silicone at the end of each dive excursion. The second one is an Omersub black silicone low volume mask, that I use in the pool almost 3 times a week for courses. I don't know when it was manufactured, because I found it 6 years ago snorkeling. It was already incrusted with sea life, so I suppose it was there submerged some months. Only one strap change ever since.
Related to snorkels I have a Scubapro Escape snorkel I bought together with the Cressi mask in 2007, used for dive excursions and pool 3 times a week. Still pristine.
