They have several benefits - flexibility being one - but are also difficult in many ways.
Moving several hundred figures, one at a time, is both tedious & time consuming. That's why movement trays were developed.

These, however, have their problems. After a large AZW game, sorting through the numerous Zulu casualties to ascertain which regiment/movement tray each individual figure belonged to, is a chore.

You also get the phenomena of "shaky figures" where, say, 20 figures sit on a large tray none too securely and any sudden lurch when you're moving the tray results in an avalanche of loose figures.
I may have solved this one. A small blob of blue tac on the underside of the individual base allows a more secure attachment to the movement base. If you remove the figure, as a casualty, a quick squeeze of the blob back into a ball, as you replace the figure at game's end restores this attachment.
This certainly works short term as I believe blue tac to be eternally indestructible, should work long term too.
