recommended Chinese input methods in emacs?

[Benjamin Rutt]

The version of GNU Emacs I'm running comes with the following chinese
input methods:

chinese-4corner        chinese-array30
chinese-b5-quick       chinese-b5-tsangchi
chinese-ccdospy        chinese-cns-quick
chinese-cns-tsangchi   chinese-ctlau
chinese-ctlaub         chinese-ecdict
chinese-etzy           chinese-punct
chinese-punct-b5       chinese-py
chinese-py-b5          chinese-py-punct
chinese-py-punct-b5    chinese-qj
chinese-qj-b5          chinese-sw
chinese-tonepy         chinese-tonepy-punct
chinese-ziranma        chinese-zozy

Can someone recommend one or two of these input methods as being
either the easiest one to learn and/or the one that leads to the
highest productivity in the long run, for a native Chinese speaker?
Thanks,
