Genome Mate for FF - advantages over FTDNA chromosome browser?

[MossyTC]

I've bought two FF kits, one for each side of my family. These are the only kits that I have, or that I expect to have for the foreseeable future.

Are there advantages to using Genome Mate's chromosome browser compared with FTDNA's chromosome browser for those kits?

Of course I will be uploading the data from the kits to GEDmatch, and possibly other sites. Again: Are there advantages to using Genome Mate's chromosome browser compared with GEDmatch's?
