Advice on best mid priced MM cartridge choice for Rega P3 (2016)


Greetings,I am interested in advice or opinions from actual owners of Rega P3 (2016 version) turntables on what mid priced moving magnet cartridge they have paired with it and have success with. I have narrowed my choices down to the Ortofon Bronze, Nagaoka MP 150, Sumiko Moonstone, or Audio Technica VM540ML. I am not interested in MC carts, and have read that Grado does not pair well with Rega.

Currently I have the stock Elys II mounted. It has been solid, but I am looking for a more dynamic sound. I understand there may be spacers required for VTA, etc. for various cart choices. I am most interested in your opinions on the sound quality of the carts mentioned above-what do you think sounds great with this turntable?
Thank you for your help!

There is only one cartridge here that has an actual return policy. A policy that says, if you don't like it, return it for a refund.

And that is the new Teo Audio MM CBP Cartridge. 

We believe in it enough that we don't think that anyone will return it.  Even if they normally use cartridges that cost 2-3-4-5-x times as much. Be they MM or MC in type.
I used a Denon Dl-110 on the same table, sounded great. People seemed to like the Nagaoka better though.
I went from Grado Red to Ortofon Bronze, best $500 I've spent on audio so far.
