Ive had all 3 putters at one point and time and for me the L96+ Versa is the best . But thats for me . I didnt like the Nike putter because I couldnt feel it when putting funny as it may sound . So after a month of playing with it I went back to my 96+ Versa and with no regrets .
Others will swear by the Nike M1 as the best putter ever and others will tell you its the Versa . So you may just have to try them both as rentals and then decide . Personally I hate wasting credits on rentals but this will be an exception . Your putter is different from all of the other clubs in your bag . In fact you will use it more than any other club that you have .
So you will have to find the one that fits your putting style the best . As a miss the ding player even when putting the Versa is a champ . The L96+ is the last putter you will ever need to buy everything else is about reading the greens and breaks properly .But with the Versa you can putt either way be it miss the ding or hitting the ding its tops .
To me the M1 is a more ding style putter in spite of the fact that it has the same increments as the Versa thats about it .Now if thats your style of putting then again you can get that using the Versa . So as you can see Im a big Versa fan and the only way I would give up my 96+ Versa is if WGT gives me a better one and the M1 isnt it .
Hope this helps you out but again you may have to rent them both and then get what works best for you . Its your game so play it well . :-)
