I have used a number of file systems over the years.
from ext in the pre-1.0 kernels through Reiser and XFS.

And I have had problems of one form or another in all of them but none 
managed to blow away all the data that was less than 3 months old after 
a power failure.

fortunately the several hundred files were not critical.

Before this my take on the various BTRFS complaints were that people 
were likely using corner case features.

But having my data scrubbed without a hardware failure is just down 
right confidence destroying.
If I cannot replace the functionality of ext without having data 
corrupted then I am not going to use any of the other wonderful features 
of BTRFS.

Not sure how you would define it but my take is that bulk data loss with 
no indication of errors is the opposite of solid.

just my $0.02
