Quick nub assemblies are called out by their alphanumeric code. "M" stands for "Midget" while "D" stands for Dwarf. Midget is smaller than dwarf. The number "4" generally means 1/2", but can be used for additional sizes. The number "5" generally means 5/8", but is often used for 9/16" swaged since swaged cable tends to be a little oversized.
One size is not better or advantageous, it's simply a matter of fit. If you're running regular cable from 7/16" - 9/16", then you can choose between the midget and dwarf sizes--M4 and D4 respectively. Most choker hooks are midget-based, meaning they work with midget nubs, so the M4 would be the right choice.
If you're running regular 5/8" line, most use a D5 dwarf nub. For 5/8" swaged, many use a B5 which is larger and accepts the oversized line better ("B" stands for Bantam).
