While both work, each has its own pro's and con's. Glass is durable, easy to clean and sanitize, can be used for vacuum degassing and is considered better for long term storage. However, glass is heavy and it breaks. Plastic is lightweight, has a larger opening and is cheaper. Plastic is less durable, can scratch and give bad things a place to hide and is not as environmentally friendly.
