I use stainless chopsticks myself.
I noticed that they're more punishing to bad form.
What I mean is that since they're more slippery they forced me to grip them harder which hurt my wrist over time. (My wrist is already bad from using a computer for work all the time).
But when I fixed my form, I can hold the chopsticks with very little force and they're just as comfortable as wood chopsticks now.
So if you're wary about, or not enjoying stainless chopsticks, I encourage whomever reads this to keep playing around with different grips.
