From my knowledge SSD's transmit data faster and are a lot better shock durable as no moving parts and you don't have to worry about high altitudes with SSDs. So anything you can imagine that would use the speed of data being sent back and forth faster would be ur advantage. It's not just loading times. You can save files faster.
For my use of a computer no a SSD is not worth it but I'd love it just for the fast OS boot and for faster app loading. I really don't need it for much so I'm waiting out. Also I just want an excuse to open my computer to add new parts.
