Is it better to exchange money in the US or the Philippines?

Hello there, I'm curious about something. I'm planning a trip and I'm wondering whether it's more advantageous to exchange my money into US dollars or Philippine pesos. Could you shed some light on the matter? Factors like exchange rates, fees, and convenience of accessing cash or cards in both countries would be greatly appreciated. Additionally, if there are any specific tips or precautions I should be aware of, that would be fantastic. Thanks in advance for your help!
