How to compare scanner stats for photos

I want to scan my photos in a quality way. I have a Canon MG6320 printer with scanner. I don't know how to compare this with an Epson V550 photo scanner I am considering. Can anyone advise whether the Epson would be a significant upgrade worth purchasing ($112 refurbished; $170 new). I think the usability of the Epson is better than the Canon, but will it produce better visual results?
