Better, IMO: Arrays.stream(filters), for 2 reasons:

(1) Arrays.stream has options startInclusive/endInclusive bounds.
If you have an array buffer that's not necessary full, then you
need the endInclusive (though admittedly an alternative is Stream#limit).

(2) As a matter of style, Stream#of is a varargs method: It takes a
variable number of T, not an array of T.  True, variable number of T
is implemented as (and effectively overloaded as) an array of T,
but Java varargs is a bit of a hack and and using ivarargs to pass a
single array is less readable I think.
