RCM Sensore Prelude OR Zesto Andros PS1 Phono?

Hi All. I have the opportunity to purchase either one of these two phono stages. My problem is i would be doing so with only having heard the RCM Sensor Prelude. Whilst i think this is a great phono stage i am wondering if anyone has heard both the Sensor Prelude AND the Zesto Andros in their setup and if they could convey their thoughts to assist me with my decision making process. I can't find any online reviews that compares both of them in the same review. There are great individual reviews for both of these items. So keen to get other perspectives and especially keen to hear if anyone has heard both? Thank You
