Personally I love the Nike Method, the meter is slow and the putter is accurate (pity I am not) but I am a ding putter. I did think about the Odyssey but have not tried it so cannot comment but still hear the meter is not as slow as advertised. If you are miss the ding putter it may not work as well for you, although sharp breaking downhill putts I use this method.
The downside of the Nike is putts under 10 feet - you have to hit harder just to make the hole, so takes some adjusting too. But otherwise a very good putter IMO.
EDIT - whatever putter you go for, stay with it as all new putters take getting used to.
