I've been jumping around from one tab management tool to the next. Tab Outliner, Raindrop, Cluster, Tab Session Manager, the last one I used was Workona, even paid for the monthly on it.

All of them had their drawbacks, although Raindrop and Workona did have the depth I required, but both of them lacked in workflow. They were slow to load, and bottlenecked my work, especially during Zoom meetings.

I tried the free version of TabExtend before buying. I appreciated the organization structure for tabs, but where it shined was the extremely low memory footprint.

It loaded extremely fast, no lag time between clicking the extension button and seeing the group of tabs I needed to access to. There's still room to improve, but compared to the alternatives, TabExtend still beats the rest.
