I tend to use Multi-Purpose for everything, but my first lot of sowings of
small seeds look to be struggling a bit with the large particle size.

Do all seed and cutting composts have a smaller particle size, and does
this make a big difference?

Seed composts, yes, but not necessarily a positive one :-( Too fine
a particle size leads to compaction, and the seeds will fail. I have
some Westland 'John Innes' young plant compost, and shall take it to
a tip when they reopen - it's virtually pure silt and NBG.
