Yeah it comes down to what wep you got and also your personal preference in playing around the procs. I personally dislike the increasing agility of Renataki as its yet another thing i need to manage and id rather have a 20 sec static proc window to play with (especially when used alongside RoR)
I would recommend anyone new or struggling with dps to go with Juju/Talisman for that reason. (but ymmv and all that)
