Onibaka - If you merely look at someone's score it can be misleading. People often comment on my score, but I always tell them there are people with half my score who who have a better gamerscore than me, because if you actually take some time to look at their profile you can see they have accomplished more things and are clearly better gamers.
Gamerscore covers both bases for me. It may seem superficial,but it shows the volume of games you play and, given the proper scrutiny, your gaming prowess.
I have a PS3, but I rarely play it. I haven't switched it on since GoW3 and don't intend on doing so again until UC3. Clearly my preference is with the 360, however, (I hope) I'm old enough (41) and mature enough to be over the whole fanboy thing when I say I'd take Gamerscore over Trophies every day of the week.
