by default setminus is

That is a smallish , set as a binary operator with the same spacing as -
but backslash is
DeclareMathDelimiter{backslash}{mathord}{symbols}{"6E}{largesymbols}{"0F}
That is a large that can grow with left right but otherwise set as an ordinary symbol, so acting like |
So typically the first is for set difference H ∖ G and the second is for cosets H G

In the Computer Modern math font family, the shapes of setminus and backslash are identical. (Aside: the vertical size of backslash can be modified by left and right directives; that's not the case for setminus.) That does not mean, though, that the symbols get typeset identically. This is because backslash has status mathord ("math ordinary"), whereas setminus has status mathbin ("math binary operators"). Having status mathbin means that in combinations of mathord-mathbin-mathord -- as in Usetminus V -- a "medspace" amount of whitespace gets inserted on both sides of the setminus symbol.
In contrast, TeX does not insert whitespace between math atoms (to use a TeX jargon word) of status mathord. Hence, no extra whitespace is inserted in Ubackslash V.
