Hi Dave,
it really depends on the type of diving you usually do.
When I got my drysuit I got Rockboots because I knew that I would do most of my dives from shore or with considerable hiking distance.
If you dive from a boat or you cave dive in Florida, turbosoles are certainly easier to use and quicker to put on.
But if you do lots of shore divers with quite slippery and rocky entries, I would take the socks and replace the rockboots with a sturdier boot. I found a boot here in France at the local sporting goods shop on sale for 3 euros, very solid, called pataugas. Very much like a Converse All Star shoe.
I also have weak ankles and I found that this type of shoe gives me better support, especially when carrying heavy gear on my back. I have no problems finning and cave diving with them. It's only that it takes longer to dress and it's two more possible pieces one could forget when travelling.
YMMV
