Is the F5 more accurate than a F3?

There's quite a long thread dissecting this exact question (and how it compares to the 735xt and 935). That's over in the 5/5S forum.

Thanks

I'm relatively happy with my F3 running 6.90 (received March 2015), but i wonder if the GPS track from the F5 is more accurate. I have some bonus and tax money burning a hole in my pocket.

Why not run the latest version 8.20 software?
