Hey Latte!
It really depends on your preferences. Just as the pole itself is part of our equipment, the shoes can be just as tricky to have, and use. And, just like there are different preferences to pole size and finish, spin or not, it can depend that way with shoes, too!
I really enjoy my Ellie's, but they are they only shoes I've ever had, so I can't specifically say whether they are better or worse.
I also know that use of shoes is going to be different when training. Like, if you started learning spins when you had pants on, and then switched to wearing shorts, it's quite the different experience, and you need to subtly adjust things to accommodate. So it goes with shoes, too!
If you have the chance to try some at a studio, or can pinpoint specific issues you may have with your current shoes, you could get some new ones and keep trying!
