Should I keep jorn as my commander

Sooo I have a snow deck that’s around low 3 to high 2 in comparison to my pods of friends. I like jorn but honestly 9/10 times he does anything is because it’s in simic basic colors, just wondering if I should instead tune the deck for isu the abominable and see how I like that compared to jorn, jorn is great due to the whole double mana early game and if you are ahead and stuff gets removed you can then get it back if you recast him on his back side. It’s great and fun but it’s just lingering in the back of my mind that a huge yeti could Be my commander and there’s a lot of nice white snow cards I want to try. I just want to hear y’all’s opinion on it and see if I should either A. Try to upgrade and tune my jorn deck a little more or B. Go break it apart to make isu and try and see if i like that more
