I’ve played with the PS85 for most of my life. I think each iteration was progressively more flexible, so the answer to your question depends on which version you want to replace.
I play with two matched ones from the last TW batch, and I’d say the two rackets that feel and play the most similarly to them is my Yonex Vcore Tour G 330 (orange), so I can’t say if the current Vcore 330 is far off, but I imagine it’s pretty close too; and the Volkl Power Bridge 10 Mid, which is the best bang for your buck right now. The PB10 is probably the most similar in swing speed, weight, spin, and plow through, but it’s more forgiving than the PS85 and it’s more flexible, which I like, but just string it 5lbs tighter and you’re good.
(Edit: the Phantom 93 14x18 doesn’t feel like the PS85, but it would be a very easy and rewarding transition.)
(Edit #2: no 18x20 frame, no matter how good in it’s own right, will feel or play like a PS85.)
