I do often see benchmarks comparing them and usually Pi comes out on top, but I think the benchmarks are generally testing one moderately sized clear task. Pi is minimal and great in that situation.
For more general usage, where tasks are not clear, you might interrupt at any moment to steer it, etc. benchmarks are harder I guess. I personally love pi because anytime there's something I don't like, I spin up a separate session and fix it.
E.g. I've found the "reply in simple technical English" hack amazing but I have to keep saying it over and over. So I had an agent write an extension in about ten minutes that appends a short hidden message saying all user and dev facing text must be in STE, apply that without talking about STE. Works amazingly well.
