16-45 versus 20-35 - better sharp?

i'm finding a good zoom. sharp open wide.

about you, what is the better between 16-45mm and 20-35mm ?

(or if you have more info, give me about another sharp zoom)

I have both lenses so let me summarize what I consider the relative pros & cons:

DA 16-45mm f/4
Pros:
Affordable wide angle
Sharp in the center and edges
Versatile focal range
Quick shift
Way better value than the DA* 16-50 f/2.8

Cons:
Moderate size, lens extends at 16mm
A bit of barrel distortion at the wide end
Slight vignetting wide open
Some CA
Tends to underexpose slightly in matrix metering (at least on my copy)
Tendency to hot spot in IR photography
Lens barrel can obstruct if built-in flash is used

FA 20-35mm f/4
Pros:
Very compact and small, lens doesn't extend when zoomed
Punchy colour rendition
Good sharpness, especially in the center
FF coverage (usable on film cameras)

Cons:
Narrower focal range compared to the DA
A bit of barrel distortion at the wide end
Sharpness matched by the DA but a little weaker on the edges
Not so cheap, if you can find one...

Both lenses focus fast, both have about similar build quality. I like both and although at times I've been tempted to sell off the DA 16-45, it has always proved useful on holidays.

creampuff thansk for info!

yes, 20-35mm is expensive. i thought that 20-35mm was better of 16-45mm.
but i think now that they are similar in sharp.
so is better 16-45. right?

Practically speaking both lenses give very good sharpness and optical quality. However if I can say it, they have slightly different personalities. The DA 16-45 is more utilitarian and gives predictably good images, whereas the FA 20-35's strongest characteristic is the unique color rendition. You can't go wrong with either one of them but I'd say go the cheapest and widest, which means the DA.
