"Hard to tell without trying it out," I'd say.  Maybe pick some random 
test now done via testtool and see if it can be ported to 
subsequenttest's "pure UNO" approach and is better afterwards.

The root problem here probably is that in some cases appropriate 
notification channels are missing, so test code inserts little waits. 
Some other places are probably "test didn't work first, inserted a 
sleep, test then worked, no idea why" that should rather be analyzed fully.

On the other hand, this did find errors in the past.  ;)  (Some menus or 
drop-down lists maintained items in the order as provided by configmgr, 
relying on configmgr providing them in a specific order; after the 
configmgr rewrite, the items were in a different order, and the actions 
associated with the items no longer matched the items' text...)

Yep.  Ideally, such higher level tests should be understandable, 
writeable, and maintainable by both QA and Dev folks.  testtool is 
probably something that neither camp particularly likes.
