There can be sooooo many factors that make people give up wearing any interface at any pressure.someone I respect (local sleep clinic) keeps telling me that most who try them eventually give up - her reason is issues like 'windburn' etc: for people like my self on high pressures.
There sure are a lot of people at high pressures who post to the message boards, happily using nasal pillows interfaces. Or at least as happily as any of us can feel about any mask of any type.
Given how much better nasal pillows interfaces can seal at high pressures, and how much more comfortable they can be to wear than most nasal masks are, I'd sure be giving one or more pillows interfaces a try, no matter how high my pressure.
Easy for me to say, "give 'em a try"...it's your money.
At any rate, don't judge all nasal pillows interfaces by the first one you try if it doesn't work well for you. As I'm sure you've noticed, different interfaces work differently on different people.
I'm sure you've also taken note of the things people use to make nasal pillows "feel better" - Ayr gel, KY jelly, Neosporin ointment, heated humidification, homemade straps, garbage bag ties, netting..... LOL!!
