Solid Al caps have a similar crowbar failure mode and create much
heat and gnashing of teeth from any suits that happen to be in the
room. They seem to be about as tolerant of abuse as their wet
cousins, which is way ahead of tants.
Personally, I tend to use a small wet electrolytic plus a ceramic in
places where you most often see tants. The combination has similar
overall  response and they are far more generic in use.
