Both great wedges, but i'd recommend the vokeys because you have the choice of different sole designs- have a look on vokey.com may'be, they have some new ones for 150 dollars, but you can choose from a wider variety of sole grinds. IMO the vokeys look much better aswell!

It certainly can help, the nike method putter in particular uses special grooves to get the ball rolling smooth and fast, but loft on the putter is probably more important for smooth roll in my opinion.
