In my opinion, (and that of my wifes....yes she eats herring as well believe it or not) Moisheles is by far the best herring that Israel has had on the market in a VERY long time.
Its a little hard to come by but im sure someone on these boards can point you in the right direction..
I had it at a kiddush, luckily i got there one of the first because it was all gone very quickly.
