You definitely get a better plating by using a electroless Tin 
plating.  Using solder and an iron produces a bit of waviness or 
bumpy surface (not to mention the flux which needs to be scrubbed
off).  The elctroless Tin plating results in a very smooth layer.

I used to have the recipe for a wonderful electroless Tin plating 
solution based on Stannous Chloride, Sodium Chloride, and Sodium
Cyanide.  Now that I'm older and wiser (and still alive), I no longer
use that particular material.
