Which is better, remote sensing or tilt photography?

Both can be used, each with its own characteristics.

Remote sensing is a technology to identify and measure different parameters without direct contact by detecting optical radiation with different wavelengths. Tilt photography technology is a high-tech developed in the field of international surveying and mapping in recent years. It subverts the limitation that orthographic images can only be shot from a vertical angle. By carrying multiple sensors on the same flight platform and collecting images from five different angles, such as a vertical angle and four inclined angles, users are introduced into the real intuitive world that conforms to human vision.
