Ggavetti, I own the SF G's and have listened extensively to the 7Es3's.... Really 'like comparing apples and oranges' as the old saying goes.
If you listen to Jazz and vocal and strings, IMHO the G's are just about unbeatable and frankly to me in a different league to the Harbeths. Harbeth's are very good and have a " BBC" sound. I like this sound, BUT again IMHO it is a coloration. You can also hear the contribution of the box with the Harbeths.
EAR make good electronics and will match well with either speaker. In the end, the best advice I can give you is to go out and see if you can hear both speakers for yourself.
