Both have one-time/lifetime purchase options. Taskbar is $25 one-time with a free but expiring older version. ActiveDock's one-time prices are $15 (1 year of updates, but usable forever) and $60 (lifetime updates).
Thank you for mentioning my app (https://lawand.io/taskbar/). It's been around for a couple of years and it's considered the best alternative to uBar according to the extremely positive reviews by my users
All in all it does not seem like a polished app to me. I tried using it and I could not bring myself to buy it. The main reasons being its issues with multi-monitor support and waking up from sleep. boringBar does not have these issues.
