I've found Geocodio to be a good option too, especially if you need to do batch processing: https://www.geocod.io/

Same here. Not using anything now, but when I needed it, they were a good value, and easy to use. They sponsored a PHP conference I went to, which is where I heard of them, and became a customer. LPT: conference sponsoring does work ;)
