Cloud helpdesk also does not support escalations.

As far as best - this is subjective, meaning what you might consider the best feature, I might not - so you will need to be clearer on what your business needs.

If you want to invest in a product, free may not be the right choice, there are many helpdesk systems out there with many more features, but you need to pay for most.

I’ll recommend a few though, mostly all based on the same code.

Specifically this part

Update [Nov 9, 2023]: As a part of the continued degradation of supporting services for the Desktop app, on Dec 1, 2023, we will take services offline, impacting the below functionality on all Desktop apps.

Desktop apps will be unable to generate alert notification emails or any other emails currently being sent by Spiceworks mail services.

Desktop apps will be unable to authenticate using Spiceworks authentication services (you will be unable to add new Desktop app users, register new installations of the Desktop app, manage/reset user passwords with Spiceworks authentication services).

Desktop app will be unable to install shared plugins, shared reports, or shared language packs from the Spiceworks App Center.

There may be other unanticipated effects on Desktop apps, potentially including impacts to core functionality. As we communicated in Dec. 2021, we recommend migrating off of the Desktop application.
