I was on team 360, for a lot of the common reasons. More so than the console being super expensive, and some of ports being buggy. PS3 was the era when SCE started to shift away from publishing it's more quirky exclusive games and moving towards titles with a mainstream western audience in mind. I felt like a lot of the big games they pushed shared too much in common with a lot of other big multi-plat games then, and kind of blended in with the crowd. Nothing jumped out and made me think that I needed to have a PS3.
I felt like the console ended up as being a very similar deal to the 360, just with a heap ton more J and S RPG imports from Japan in the later years, which I have virtually no interest in. My collection consists mostly of exclusive titles. There's some interesting stuff in there, but honestly I've yet to touch most of it. I have very little, to almost no experience with the console. I picked up mine, a used one from GS in 2014... and my controller has sort of a "drifting" problem with one of the sticks. It does have an intuitive DVD player function, I will say.
The multi-gen backwards compatibility on my 60GB is a very nice touch, but inevitably with some games you'll need a device like a Retrotink to display some of those wacky resolutions on older PS games that modern day TVs don't understand. More than a few PS1 games I tried to play using my PS3, didn't display video at all.
