I can only comment on their usage on Citroens; for which they usually run a bit cheaper. That's too bad.

The dizzys for Citroens have VERY specific advance curves due to unique carbs and rudimentary interfacing with hydraulic semi-automatic gearchange. Then they got D-Jet, and a big upgrade in cc's... The DS/ID lasted 20 years so there are a lot of worn-out, mis-matched dizzys out there and a lot of cars suffering as consequence. Furthermore, if you ever overbore/resleeve or reprofile the cam and use an original dizzy your car just won't run like it ought to.

So a more efficient spark, adjustable advance curves and solid state electronics have been quite the godsend.

You just go about the usual static timing, but remove your old distributor, install the new; there's a little red LED to help you static time, and a switch to help you select the advance curve of your choice; either stock for your year or most suited to your engine (thru trial and error).

You may have to install a new coil, but usually not.

I think it's a good alternative to rebuilding your distributor; but right now isn't dire straights for Bosch dizzys. Maybe an extravagance on a B20, but definitely on the 'must have' list for my Citroens.
