You need to test it first so I wish NYM adds daily plans.
In 24 days my monthly Mullvad subscription will end. Then I 'll try NYM. And finally I will conclude in one of these 2, unless I find another option to test. With Mullvad, I don't have a speed limitation so far, I am more than good with it. In terms of privacy, as I said I paid with XMR, using TOR browser, without an email registration and essentially I am "unknown".
I suppose that by now you are already trying NYM, so looking forward to your feedback. Cure53 have also recently released an audit[1] where most of NYM was audited and, in their conclusions, there's an interesting take:
Nym's decentralized approach to servers hopes to mitigate the risk of centralized logging rather than depend on the possibly misleading assurance given by a no-log audit of a centralized entity. However, even decentralized servers can not be meaningfully subjected to a no-logs audit.
