Help! Can't make mind up on a new grinder

I'm currently using a K-ultra for my brews. I've found myself desiring a new grinder to explore different profiles. I would like to go electric for workflow purposes. I am thinking of a 078, Ode Gen 2 stock, or Ode Gen 2 SSP. Is the price hike between the ode and 078 justifiable? Will I find myself desiring an upgrade if I land on the Ode? Stock or SSP burrs on Ode?

I am one that goes pretty deep down the rabbit hole, so this will likely not be my "endgame". But I do want to invest in a quality product that is going to yield good results for several years.
