General speaking, Does sharpness on DA21 on par with F28 (or any sharp 28mm)?

FoV is not comparable.
This is big part of the answer. 21mm is much wider than 28mm, so you cannot really get the same amount of detail. I have the DA 21mm and find it sharp, sharp enough, sometimes very sharp, but not brutally sharp. DA 21mm has its weaknesses, like f3.2 and some distortion, but its main strengths are super compact form, and amazing contrasts and colors. These are the main selling points. If you only care about sharpness, get Samyang 20mm or something like that.
21mm vs. 28mm? Both. I have M 28mm, and it is so different I will keep both.

I don't know about the 20-40mm, though. Some people find it lacking, but some really love it. I am prime guy, so I will stick to primes. If you prefer zoom, go for it.
Basically, I doubt any of the lenses you mentioned will disappoint you, unless you have really weird expectations. You should just get one, then another, and so on. Good luck
