I got one of those diagonal-ended TCT chisels on the recommendation of a
local electrician, only to find out that what had actually been
recommending was a square-ended one (still with 3-4 TC teeth).

Comparing the two, they would be about the same for removing bricks and
chasing slots, but the square chisel is definitely much better for box
sinking because it's very easy to make flat-bottomed cuts. At a guess,
the square one would probably be better for this particular job as well.
