Chemaxon Marvin vs ChemDraw opinions
Simple structures are needed.
If you are looking for a chemical sketcher or an alternative to your current chemical drawing application, there is no better choice than ChemDoodle. ChemDoodle works on all operating systems (both 32 and 64 bit), has one of the largest feature sets in the industry, has the most...This app doesn't have any features at the moment.
ChemDoodle vs ChemDraw opinions
Closest thing to ChemDraw functionality and, unlike ChemDraw, it works natively on Linux. Sadly, the author has chosen a frustrating atom-first drawing mechanic which is hugely counterintuitive. But if you can learn to accept it, ChemDoodle is a respectable ChemDraw alternative (unless you need to draw pi complexes).
Functionally equivalent and very similar in features. Very similar layout makes it very easy for chemists to switch
BKChem is a free (as in free software :o) chemical drawing program. It was conceived and written by Beda Kosata and is currently maintained by Reinis Danne.
The last release was in 2010.
BKchem vs ChemDraw opinions
Very usefull software. You can paste images created with BKChem in a text processor or another open source graphical software like InkScape.
BKchem is an old attempt at replacing some of ChemDraw's functionality. It succeeded partially in providing some of ChemDraw's very core chemical structure drawing features. Unfortunately, BKchem has seen no new development since 2010, leaving it in limbo.

The Gnome Chemistry Utils include six chemistry related programs:
- GChemPaint, a 2D chemical formula editor.
- a chemical calculator (computes raw formule, molar weight, mass composition and isotopic pattern).
- a molecule 3d viewer using OpenGL to display molecular models. .
JChemPaint is an editor and viewer for chemical structures in 2D. It is free and open source software, written in Java and so it runs on Windows, Mac OS X, Linux and Unix systems. There is a standalone application (editor), and two varieties of applet (editor and viewer) that...
ACD/ChemSketch is a chemically intelligent drawing interface that allows you to draw almost any chemical structure including organics, organometallics, polymers, and Markush structures. Use it to produce professional looking structures and diagrams for reports and publications.This app doesn't have any features at the moment.
ACD/ChemSketch vs ChemDraw opinions
A good alternative to ChemDraw in very limited circumstances: 1) you need it on Windows only, 2) You don't have to collaborate with ChemDraw users, 3) You don't mind looking at a confusing, dated interface. Otherwise, fine.
