Yes, i had the same dilemma. And yes, the F800GS is much much much better for daily commute. And the price diff is really way to huge. I hardly log 10k per yr so dumping 50k on a bike just doesnt sound right to me...haha.
Actually, the 800 have really great looks too. Just kit it up properly to achieve the looks you want. Also, the fuel consumption is really fantastic.
However I ended up with a 1200GS 2nd hand as it fits the budget i have. Reason is when I tried both bikes, I prefer the stability of the 1200GS much over the fun of the fun of a 800GS. Also, mainly thinking of going for some touring just to satisfy an itch. But if the 2nd hand one wasnt available, I would have booked a 800GS Matt grey from PML. Personally, black color is so not my thing, so I don't quite understand why triple black is more ex...kekekeke.
