I think it makes it clearer that you are taking a particular operation,
"sizeof", and applying it to the thing inside the brackets.

I will happily admit that this is a matter of personal taste or
preference (hence the "IMHO") - unfortunately that also makes it
difficult to explain.  But it feels "natural" to have parenthesis here.
 On the other hand, in some places where C insists on parenthesis, such
as "if (x)", the parenthesis feel unnecessary.

But I don't see it as a big issue.  I consistently use the parenthesis
for sizeof in my own code, but I won't complain about missing
parenthesis in other people's code (in the way that I /would/ complain
about "int* p, q;", for example).

It is a major detail to the human brain.  I am not sure that this is the
only reason why it makes a difference when reading and mentally parsing
sizeof code, but I do think it is significant.

It turns out that I use sizeof a good deal on types.  In particular, I
regularly want to check that the size of a structure of some sort
matches the expected size, because the structure is modelling hardware
registers, a communication block, or something else that has to have a
fixed format.  So I will have code like this:

typedef struct {
	uint32_t header;
	uint16_t data[6];
} sampleBlock_t;
static_assert(sizeof(sampleBlock_t) == 16,
			"Bad size for sampleBlock_t");

The check here, and therefore the sizeof, is at the earliest spot in the
code, as soon as the type is defined, long before the type is used.

But maybe that's just an oddity in the type of code I write, or the way
I write my code - I am generous in my typedef'ing and my static_assert'ing.

Most other uses of sizeof in my code are for objects rather than types,
but I don't have a particular objection or dislike for applying it to
types.  I usually know exactly what types my objects are, and don't
change them much, so I would pick whatever is most convenient and best
indicates the purpose of the code.

Not really (see below).

We probably agree on a great many things - but there is no fun in
discussing them!
