Depends what you like. I have always argued that a putter is the most personal item in the bag.
What suits one person may not suit another. A lot of factors including non-technical ones, like trust and appearance affect choice.
One thing is for sure, there is not one putter that can 'objectively' outperform another.
So,f or me, it has been the type that suits my putting style, found out through trying different types over the years.
- and then finding one that is so well made, that I can keep it for ever..
