Should I get a decorative firepit or a fireplace/grill combo?

We bought an outdoor fireplace years ago at Target. It’s been used at home, campsites, the beach – wherever we want to warm up and toast marshmallows. The bottom finally rusted out and we need a new one. I am torn between getting an outdoor fireplace/grill, that is portable like my old fireplace. My old one did not have a grill but I see they have that feature now, which is really convenient for a few quick hot dogs or burgers.

Or I could go in another direction since we are adding to our outdoor furnishings and trying to get high end items for the deck. I like those firepits that have stone or marble around them but they are more costly. Plus they are not portable. But they look so beautiful, like ones pictured on this site:

Both are completely different from my old one, which was a standup fireplace with a screen in front. Does anyone have a fireplace/grill or firepit with stone edges? What are the pros and cons? Thanks!
