I have mixed feelings about the 20. It is small, fast and sharp but also slightly too narrow for what I use it for.

When I received my 20mm and did some testing, I was surprised that it was a bit wider than my 14-45mm @20mm.

Some searching around revealed that the 20mm is considered to be really 18.5mm

Pekka Potka made a statement to that effect on his blog and the word spread. But since there were contradictory claims about the matter on this forum, I tested it using the method described here:

Result: The 20 is a 20, no more and no less.

You should compare the two lenses together if possible, to see if the 17mm is wider enough for you!

Richard
