What is the difference between Filecoin and STORJ?

Could you please elaborate on the fundamental differences between Filecoin and STORJ? As both platforms cater to the decentralized storage market, I'm particularly interested in knowing how their token economics, consensus mechanisms, and overall approaches to ensuring data integrity and privacy differ from each other. Understanding these nuances would help me make an informed decision about which platform aligns better with my storage needs and investment objectives.
