I think it's considered about equivalent.

The advantages of the flash one are no battery maintenance (=no
downtime every <n> years to replace it) and no "timeout" if you loose
power (but the battery backed ones are usually good for 48 hours or
so, and if you don't have a server up by then...)

Yes.

Can't comment on that one, sorry.
