I came back from Christmas in England last night and the Perry WOTR infantry were waiting for me. With the posts above in mind, I put on my magnifying glasses and compared the figures with the WF Vikings.
Firstly, both sets are excellent. Even better, many parts are interchangable. You can fit Perry WOTR heads and arms on WF vikings, and vice versa.
Plastic – identical (as far as I can tell)
Mould quality – both sets are excellent. WF is fully matt whereas Perry has some shine. There is some slight flash on the Perry standard pole.
Mould lines – Perry have very few, WF virtualy none. Neither need cleaning.
Anatomy and bulk – Height is identical. Perry are slightly slimmer torsos and heads. Perry are slightly higher waisted but this is probably due to more the style of clothing.
Heads – Quality is the same. The heads are interchangable. The WF necks are longer which means some trimming/fitting is necessary. However, that also means that they are more flexible if you want different poses. The Perry necks are quite short. I may use some Viking heads on the Perry figures to give bareheaded archers and men at arms.
Chainmail – quality and definition is the same. Perry have chain right round the arm which looks better.
Hands – Perry have moulded on weapons so the hands are very nice. The open hands on the WF figures give more options but as a result do not look as nice.
Weapons – under a manifying glass, the WF weapons are more clearly defined. This is very visible on the sword scabards.
Weapons and arms are interchangable. I may use some spare Perry archer arms to make more Viking archer variants.
