There are three variations of ways to tie a Surgeon's knot that I know
of. The easy and quick way is to make a very large overlap between the
two lines, form a very large loop, and pull the strands through together
with your fingers. This wastes a lot of tippet and leader material,
which I don't like.

A more material-efficient way is to use a relatively small overlap, make
a small loop, and thread the strands through one at a time. This takes a
lot longer.

I've converged on an intermediate method. I make an intermediate size
loop and use my hemostat instead of my fingers to pull the strands
through together.
