I have used a whole range of closed pcb design, schematic capture and simulation tools since 1984, including a few on SUN and Intergraph workstations. All of them touted fantastic features, but delivered the usual crap. Most of the advanced features like auto place and route were always a load of rubbish. So, in effect what you need is good editing features.
PCB has all of em. But the best part is this: the files are saved as text files. Thus replacing or positioning a component is just a matter of opening text editor and changing a few coordinates. Eg. very very useful for precision positioning a component in a large dense board.
Yes, We use only placement and manual routing features. The 'auto' features are always crap. My main worry is to import old orcad / protel files.
