It is dependant on your preference and what your looking for.
Every creator is different and offers their content set to specified choices they made. So for one Patreon that loves the services there can be another who is unhappy.
The best way to make sure you are happy is to thoroughly read the details in the subscription options. Be aware of what you will get. If you have any questions ask prior to purchase. The creators are happy to answer questions concerning what they are offering.
Many creators are on several other platforms. Pick a creator that you are already familiar with. Or check their other profiles to get a fuller picture of what they do.
Many creators have a first level subscription option that is very affordable. And you can cancel before you are charged for 5he next month if it is not what you want.
In my experience patreons are happy with the service and tend to upgrade after the first month in order to gain the additional benefits. It is a different experience in most cases, because most creators offer communication with them directly. This is probably the biggest reason I find patreons stay.
