Running Styles - Impact on Gameplay?

I've been looking into the different running styles for RBs and the impact it has on the run game. I've personally felt and have heard others share that cards like Josh Jacobs (Default running style) "play better" than CJ2k (Default Stride Loose running style), even with lower stats and similar body types.  IMO Josh Jacobs' 98 accel feels smoother and more explosive than CJ's 99 accel, which has made me wonder whether their different running styles could be the difference since all stats (acc, cod and speed) benefit CJ2k. Even other players with unique running styles (i.e. uncommon ones) such as HB Vick and WR Deion (Short Stride Bread Loaf) seem to just move more explosively than others. 

Has anyone heard anything official or done testing to determine the difference in running styles? Are there certain RBs that you are great with and others you can't seem to make work? Would love to hear your thoughts.
