Well, I don't have download figures, but it is quite popular.
What does it offer? Well, the same kernel, and YaST.
What can you do with YaST on live boot? Can you use it to manage installed system? If yes, I missed how to do it. If not, what use it has?
chroot to the installed system, do things. Or don't, and configure some things in the rescue system. You can use the partitioner module, for example (I did). I installed packages on it, using zypper or rpm (I don't remember which).
Kernel ... OK, that is valid argument.
The same tool set as the computer under repair. Some things requires similar tools and versions, but others are simply more familiar.
That's really too vague. The only truly unique tool is snapper - can you use snapper on rescue medium to manage your main system(s)?
I don't use btrfs, but I do use XFS repair tools. Yes, of course they work. In fact, people on 13.2 had to use TW rescue image to repair breakage on 13.2 btrfs root filesystem, unrepairable because of bug on 13.2. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
