As always, it depends on application - Running a carb never hurt Stuart Clark on the strip, nor Hoolio Geordio (or whatever his name is) with his carb/NOS setup, and I've yet to see any efi'd GTT breaking records on track.
A well setup carb' will give equally good cold/hot starts, and likewise, good driving manners with respectable mpg. I was getting close to 400 miles to a tank out of Whitey, and that was driven (and started on the key) day in, day out come rain, shine or even snow.
The o.e Renix ignition map isn't that bad, and of course has limitations, but again it comes down to what you want from the car. It's relatively easy to advance/retard the complete map if needs be, and I'd say, imho, for 99% of people with gtt's/c1j's, that's all that's required.
If you're prepared to pay out for a full blown efi setup, imho again, you might as well ditch the c1j & fit a newer, already efi'd, possibly larger displacement, engine into the bay instead & go from there.
As a last point, it's a ~25 year old car - How far down the line d'you want to go with trying to modernise it, before you lose the appeal & character of the car?
