If the developer loses interest there is at least the possibility that someone else will pick up the torch.
Pro tcmd-like multi-rename tool (CTRL+M)
Pro DC uses TCmd plugin API
so you can use documentation from Total Commander for writing plugins. WCX (packer), WDX (content), WFX (file system), WLX (lister)
Pro It's that good, you can replace tcmd on windows too
Pro Very sophisticated
Although it is lightweight and simple to use, it can do very sophisticated tasks, like copying files from directories which have a certain extension or file size or have a certain text pattern in them. Also, it's very customizable and stable.
Pro Closely follows TotalCommander UX
For instance, the 'Settings | Layout' pane is quasi-identical to TCs.
Pro Source Code written in (Object) PASCAL
It's all a matter of perspective. I'm not for an argument about IDE's, frameworks etc, but to me that's a big plus. I think it should be a tie, it's either a pro or a con or should that be neither a pro nor a con. It just depends on context.
Softpedia labels Vuze as adware due to including the Vuze toolbar and install promotional software.

Vuze includes Tor-support which is inappropriate for torrenting as clogs volunteer's bandwidth and exit nodes by default block standard BitTorrent ports.
Con Only Supports Windows
Does not support other operating systems.
Con Not Open-Source/Libre
Is proprietary software.
Con Inactive Development
Latest release is from 2017.
Con Apparently only one developer
Con Much slower on Linux and Mac than on Windows
Con Can't edit files on remote FTP servers
Con Source code written in Pascal language
But this does not affect users negatively. It's just programmers problem
