I don't have like numbers comparing..
But really I've said Pyrex due to the fairly large surface area, and the long flat sides with rounded bottom. It just helps you scrape it all. Of course you could just save what's left for the next run but in that time a lot of air hits it etc and it won't be as good
But it's up to you. Use a crock pot if you want, a bit harder to get good airflow though with the high sides
