I'm trying to choose a free schematic drawing software, and like the way these two look. I've read related questions about circuit drawing software as well. I like Fritzing, but it lacks some components. For example, I cannot get that RS232 component into it.

eagle and fritzing. – markrages♦ Oct 24 '12 at 3:01
@markrages Thanks. I use Fritzing, but it doesn't seem to give me either of those results. – capcom Oct 24 '12 at 3:03

Hm, what's up with the down vote? People, if you down vote, please comment with a reason so that we don't make the same mistake twice. – capcom Oct 24 '12 at 3:04

First one is Eagle in default colors. Second looks like fritzing to me, but could be Visio or Inkscape or such. user submitted parts: code.google.com/p/fritzing/issues/detail?id=875 – markrages♦ Oct 24 '12 at 3:11

The top diagram is drawn in Eagle. Eagle is scalable and libraries are freely available. Creating own libraries is also fairly easy.

Second diagram I'm not too sure but it could be drawn using ms-paint. Drawing style is more enthusiastic than professional.
