I should say that the Peter Pig figures are perfectly good (http://www.peterpig.co.uk/ecw.html for the range) it is just a matter of taste that I think I prefer the Blue Moon ones which were not fully released when I got the PP figs.
Additionally I have a load of additional ECW figs from an unknown manufacturer but are about the same size as the PP ones - a shade larger and chunkier.
Pictures below with the few figs I have painted with a comparison shot with Testudo and Donnington for size.

These are Peter Pig.

The unknowns.

Size comparisons: Donnington, Peter Pig, Unknown, testudo.
I have available (if I have counted correctly ...) all 15mm:
Peter Pig Figs
39 cavalry mixed hats and helmets
4 generals and 4 trumpeteers
2 light guns and 6 crew figs
4 generals and 4 trumpeters
26 pikemen
65 musketeers (no rests)
7 standard bearers
5 foot officers
5 drummers
Unknown manufactuer(s)
51 armoured (mostly) pikemen
5 standard bearers
83 musketeers
7 foot officers
3 drummers
Plus the 2 painted units in the pics.
Will sell at Peter Pig unpainted fig prices less 10% list price (p&p additional if necessary). Happy to split into sensible batches.
