Yes. if your GOAL IS STRENGTH. Then 5/3/1 is pretty much the best at this point. It has the most linear neurological and obviously muscular adaptation to the "three main lifts".
Wendler is a bit nutty with his nutrition until his 2nd edition of the book where he changed his mind about being lean and healthy (he used to say it doesn't matter what you eat). And, I met him at a recent CrossFit "tournament" and he looked lean, healthy and strong as all hell.
I think his program is also easy to understand and follow as he breaks pretty much everything down and his percentages are easy and quite attainable in the progression department.
His inclusion of the deload week is fantastic as are his numerous "Assistance" work outs, I think he calls them.
I have a modified 5/3/1/ program with my own assistance work somewhere.
