Who is more knowledgeable and beneficial to the Ummah: Sheikh al-Islam Ibn Taymiyyah or Sheikh al-Izz ibn Abd al-Salam?

The two Sheikhs are venerable scholars. Preferring one over the other in terms of knowledge and benefit to the Ummah requires knowing the results of their work, the level of their sincerity, and the level of their studies, which is not possible now. Therefore, it is obligatory to emulate the Messengers and the working scholars, and to raise generations that follow their methodology, and to direct energies and time towards what results in action.
