Why was pasteurs experiment better than spallanzanis?
Pasteur's experiment demonstrating spontaneous generation was considered better because he designed a more controlled experiment with swan-necked flasks that allowed air in but prevented microbes from entering. This disproved the theory of spontaneous generation more conclusively than Spallanzani's experiment which critics argued could have been affected by lack of oxygen.
What is Pasteurs experiment?
Louis Pasteur's experiment on spontaneous generation in 1861 involved boiling broth in a flask with a curved neck to prevent dust particles from entering. The broth remained uncontaminated, disproving the theory of spontaneous generation and supporting the idea of biogenesis, which states that living organisms can only arise from preexisting living cells.

It showed that microorganisms can only enter the flask as airborne particles.
How did Pasteurs experiment answer the objections raised by supporters of the vital force hypothesis?
Pasteur's experiment permitted air from the outside to mix with air from the inside, which would have allowed any "vital force" to enter and cause the broth to become cloudy if there were such a "vital force.
