Orhan,

The differences between Evolution & Professional (click on Compare our solutions below buy now buttons)

But this does not explain why I chose the Pro version.

I use it because I can create a backup as often as I want and in case of catastrophy I can restore from backup without copying and renaming files. I need the extra control (more breakpoints) and the control over which cells appear side by side versus one above the other at various resolutions. I can add multiple views of a single cell  and make them selectable or a slide show.

Evo works great, but the pro version offers greater control to finesse the project (as well as the features I do not currently use if the need ever arises). Every website I have done could be achieved in Evo, but with Pro I can make them look a little better.
