Yeah, the TOEI clones are quite different from the manga ones. In the manga it's an attack that just spawns extra copies, ala Doflamingo's string replica. In the anime it seems that to make the clones Kizaru must necessarily split himself up, which logically means splitting his strength between them – TOEI Kizaru can't stay full-power AND have summoned clones beside him.
The manga ones thus seem like a stronger ability overall.
Edit: upon further inspection, maybe this breakdown isn't correct.
