contrary to the other posters I do not think it will make much difference space wise
both only contain the used data portions and do not employ additional compression
there is simply no reason why it should differ
both need to be created with special tools too
iso can be burned directly
but wbfs files can be converted back easily if the need ever arises
wbfs files can be put on fat32, sparse isos can't
fat32 is the only fs supported by sneek and hbc

Isn't a sparse ISO just like a scrubbed Wii game, but it retains ISO/burnable format?
sparse files are a feature of modern fs where long continuous runs of zeros are not store
and thus take only minimal space
for programs reading writing them they feel like normal files
the os simply adds the missing zeros back if they are ever read
you can use this feature with wii isos by scrubbing the data with zeros and telling windows to make the target file sparse
what you get is a scrubbed iso thats still 4.7G big but uses much less space of your hdd
