Sea or land landings?

What are the pros and cons of the two. From here, apart from the fact that
there is more sea than land, it seems to me that landing in the sea could be
far more problematical from the reuse point of view than a land landing,
and also historically its only been used for US landings presumably as it
was convenient when targeting was not that good. Maybe its just that the
need for a wilderness area is too great for other countries to achieve when
land is being considered.

However, I'd have thought nowadays a land landing should be possible with
much better understanding of the problems.
