At least when you open terminal emulator at the bottom of dolphin it stays synced with the directory you switch to with the GUI. In konqueror is stays in the folder you were in when you first opened it, you have to manually 'cd' or re-open the terminal emulator to get it to be in your current directory. I'd use dolphin almost exclusively, but there is no way to split the right file viewing area in to more than two vertical panes, konqueror allows you to create as many horizontal and vertical panes as you need. The result is that I have to use dolphin for any work that requires much use of the terminal and konqueror for heavy file management.
And for me only recently did either dolphin or konqueror begin to read meta-data for SOME files (e.g. some mp3 tags, image file dimensions, camera info, etc.)
Konqueror 3.5x is still far and away the best file manager ever, the terminal emulator worked properly, meta-data worked perfectly, you could even edit music tags from the file manager. In the meantime KDE4 has a new tags/comments functionality that I wonder if ANYONE ever uses, but I wouldn't know if it would come in handy because the first thing I do in a new install is disable the Nepomuck Semantic desktop search shit which completely lugs my machines and NEVER finishes indexing my admittedly largish file system, even when the database begins to fill entire partitions.
