I'm not at all a Pt guy, for a unique reason: too heavy for me.
I am skinny, thus I don't have a thick skin on the wrist. Hence, a heavy watch is not comfortable at all, especially when the watche moves on the wrist.
And I think I prefer WG's hue to the Pt (but I think it is very hard to tell, it is just an impression I have).
As for the weight you're mentionning, I think it is true indeed: I wore a cheap watch when I was around 14 (but thought it was not cheap at the time!). I broke the glass so I sent it for replacement and until it returns, I borrowed a much heavier Speedmaster Mark IV. When I got mine back, I couldn't wear it anymore as it looked so cheap because of the weight I was used to.
Hopefully, I don't feel like this with gold!
But can fully understand it of course. Many members here have a much greater preference for Pt.
Nevertheless, when I consider a watch I don't really look at the material, it is very secondary to me, but its color. And the dial etc....
But I know you are a Pt fan Kari and that's cool if you can wear it!
Cheers, Mark
