Got a -84 with the 915 and a -87 with a G50.

I would say that they are very equal..
I personally prefer the 915 over the G50.
The clutch for the 915 is lighter and the shifting with a good 915 transmission is great.
The trick is to not shift up until you hit about 4000revs.
The gearbox is a bit heavy and hard to get into 2 gear at low revs but the more you rev the easier it gets!
The hard part is not to grind the gears shifting from 5-4 when it is easy to hit reverse.

The G50 is smooth all across the rev range and is possibly a little better if you are using the car as a daily driver.

Just my thoughts!
