Nothing major. The GUI is a bit different, and change properties has a few extra options, but the end result is the same no matter which of these you use to change something. Edit properties also only works on a single entity, which makes it a bit quicker to use since you don't have to confirm your selection, and it also has a nice preview of the entity.
Pity the edit Properties doesn't also include Sheets - I often wish I could more easily confirm which sheet I have placed an entity. Also, it doesn't work for symbols, again a pity.
