I like the idea of documenting my life but I have to find that balance between reflecting and living in the moment and sometimes a quick photo to keep a memory is a good compromise.
I use a mixture of iPhone & camera. The photos on this site are a mixture of a 5th gen ipod touch, various Sony Alphas & various iPhones from 6 through to 12 mini.
I like to take photos as things are happening. Often these things in the moment may same mundane but they're good to look back on. There are other times where I will put directed effort into photography by using a proper camera and ensuing optimal lighting and all the stuff which goes into it.
It means a lot of my photos are a mixture of what looks like rushed photos and photos which look like they've had a bit more prep put into them.
