Simparica Trio is also excellent for fleas/Ticks. In general, all the products sold through your veterinarian are effective and safe compared to some OTC products. What ever product you choose, it needs to used consistently, long term for effective prevention. If you wait until you have fleas or ticks, then you have a battle on your hands. Also, every pet in the house needs to be on prevention (including cats), otherwise you won't stop reproduction.
