In this paper, we investigate and compare the quantum entanglement feature and the EPR steering between the generalized photon-added pair coherent state (GPAPCS) and the superposition photon-added pair coherent state (SPAPCS) by using the Von Neumann entropy criterion and the EPR steering condition. We then use these two states as entanglement resources to quantum teleportation processes, thereby evaluating and comparing the average fidelity of these processes. The results show that both GPAPCS and SPAPCS exhibit high entanglement and steering properties, and have great potential for application in quantum teleportation. Furthermore, in some cases, SPAPCS demonstrates better entanglement and steering properties, and the average fidelity of the quantum teleportation using this state is also higher than that of GPAPCS.
