Anything that long and thin can bend with enough leverage on it. In the tear downs, I think they discovered the weak point right below the volume rockers. That's the point where most of the pictures of bends are, whether they were done intentionally for testing or unintentional.
I had a 6 Plus. It did not bend. Due to size, I swapped it for a 6. The day after getting my 6 I noticed it was bent slightly right under the volume rockers. I am extremely gentle with my phone, especially this one, so I'm 99% sure it was this way out of the box, as strange as that may sound. The Apple Store replaced it for the defect. My replacement 6 is straight as an arrow, has seen the same kind of usage, pocketing, etc, as the 6 and 6 Plus that came before it. It's holding up fine.
The Plus was definitely on the edge of uncomfortable in my pockets. When sitting straight up, no big deal, but bending over to tie my shoes, or leaning over to pick something up, I always felt it pushed tightly between my leg and waist area. I usually removed it before doing that, and it got old really fast.
Hard to say for certain about the bending. Maybe some phones are more prone than others. But after having one in my hand that was bent I'm pretty careful with how I treat my current 6.
