Specific to your question: Inclined area where flat ground is hard to find. IF there are trees, that is a strength of the hammock.
There are many threads on this forum that discuss tent and hammock pros and cons...I'd suggest reading a few.
Hammocks require more user knowledge to stay warm, dry, and comfortable. Hammocks are great for wet muddy ground, inclines, tick areas, etc.
Hammocks will freeze you UNLESS you know what you're doing and have the right gear (and experience).
Tents typically better in real storms, better above timberline obviously. My tent setups are lighter than my hammock setups for a similar temp rating.
I love hammocks for summer camping in tick and mosquito areas that get lots of rain. I gravitate to a tent for the Rocky Mountains in hunting season.
