I have not used either, but if I needed to use one, it wouldn't be Wasabi. The reasons are self-explanatory. They are supposed to be a privacy tool. Yet, they see no issues in partnering with those that spy on your transactions to determine if you are allowed to have privacy or not. Instead of abandoning that stupid idea or at least staying quite, their response involved throwing dirt and deanonymize other services and its developers. No thanks!
