Please help me to decide! (SX220 vs SX230)

I use mostly the 4.3, occasionally the 3.2.
the 16.9 i use for landscapes, seems to get a wider picture in.

I am not into picture manipulation, cropping and all that yadda yadda, so i am happy with the status quo.

I am more interested in the subject matter, and as long as it is a good quality, in focus shot, i am happy.
