MY opinion!
we service most all brands.
they all go bad. and it depends how many are sold in the area
as to how many we see.
so i cant judge, as to which are more reliable.
but this is beside the point, i am a repair man and i depend
on them breaking.
the important thing is , the ease of repairing them, and the
factory support.
and last but not least, the price of the set new.
