I still find the J3A to be the best. 14 was good, but it swung much different with the extra EL, also felt that the SS was smaller. The 15 felt the closest to the J3A but id still give the distance to the 13. the OG has a much stiffer handle, i do like it a lot, don't have enough swings on it to compare distance though.
they are all amazing bats, and now with the OG there really is a juggy to fit everyone's swing.
