I use a regular roller bag and put one camera bag and one camera backpack in it. The camera bag has flash gear, the camera backpack has camera gear. Sometimes you have to check your carryon because there's no room, but I can usually find room for at least the backpack. If you take a photo roller bag, you have no choice but check it if the overhead is full.
In my opinion this is the best way for the reasons mentioned. I do this except my laptop goes in it's padded case and then a camera bag on top with lenses inside my 4 wheel roller bag. They do sometimes want to check your bag elsewhere if the airline is out of room.
