The effectiveness and preference of diversity techniques can vary depending on the specific application and environment. However, here is a brief overview of each technique:

a. Polarization Diversity: This technique uses antennas with different polarizations (vertical and horizontal). It's effective in environments where the signal can change its polarization.

b. Spatial Diversity: This technique uses multiple antennas, usually spaced apart, to improve signal quality. It's effective in environments where multipath fading occurs (like urban areas).

c. Frequency Diversity: This technique transmits the same information on different frequencies. It's effective in environments where frequency-selective fading occurs.

d. Time Diversity: This technique transmits the same information at different times. It's effective in environments where fast fading occurs.

In terms of common preference, spatial diversity is often preferred because it's relatively easy to implement (just add more antennas) and it can significantly improve signal quality in many common environments (like cities). However, the best technique can depend on the specific situation.
