Well, the 'ß' is missing, the umlauts are composable.
Shift plus the '-key on the english keyboard (two to the right from L)
goes to umlaut-mode, then comes the vowel.

They are composable too ... AltGr-4 goes to tilde mode, then the vowel a
or o.

As even the []{} chars are easier to type than in German, the Spanish
layout is
indeed the best agreement between all of them, if only one layout should be
available.
