They are basically the same. You can use them interchangeably.

Most native speakers use them interchangeably, however, there is still a subtle difference, and when you use them depends on the context. Poor Quality: Implies that something doesn't meet an acceptable level of quality or has not met the expectation. Example: A brand of coffee is expected to be the best in the world but the taste doesn't meet the standard expected. Bad Quality: Suggests that something is not good in any way and cannot be used. Example: A brand of coffee beans over roasted and burnt their coffee beans and it now cannot be used. Low Quality: Refers to something cheaper or simpler but not necessarily bad—it was just not made with high expectations in mind or there are better alternatives. Example: Instant coffee is good but compared to traditional coffee made by a barista it is not as good. Hope this helps!
