Portrait photography or landscape photography, which needs high pixels more, and why?

Portrait photography pays more attention to people, and dealing with people is the most difficult. It's not just shooting the scenes of the characters, but communicating with them deeply and expressing their stories with photography. In communication, you can know their stories and know a seemingly insignificant little thing, which may have extraordinary significance to them. At the same time, you should use the composition of photography to set off the atmosphere, and the photography language should also be considered.
