which is the best planar iem for 150$?

hi guys, as the title says I've been looking for a planar iem that is around the 150$ or less. I got the s12 pro and hidiz mp145 on my sight, but a lot of information is kinda confusing about both. anyway, I'd like to know which is your favorite iem around this price prioritizing THEIR TECHNICALITIES exclusively and also the audio fidelity (resolution, imaging, maybe soundstage; doesn't really matter the sound firm). thx you for your help:)

(if matters, I'm planning in powering it with a Qudelix 5K)
