What is the difference between the "Balde" and the "One" io decided to go for a gauge putter but i can;t design, what are your guys opinions on these two? And also the tera? Which one is best?

Go to search and type in "gauge one" and there are few posts regarding these two putters. I'm using both at this time and to me the Balde is more rounded while the One is more angular. Both are awesome feel and the milling marks get the ball rolling without skidding. The Balde stays in the bag more due to no sight line ... personal reasons. Am not sure if both were manufactured with the same material or not.
