Ignore all the advertising and use a putter which feels right for you and which allows you to comfortably and easily find the right line and the right speed. Don't pay attention to the putter that the pros use. Putting is highly indivdualistic and you need to find a stick that suits you well.
Select a putter that helps you to sink putts of varying distances. Realize that it is normal to switch putters periodically and that sometimes changing your putter is a very good idea.
