What is the best RMM in your opinion?

Nope but I've seen enough people complain about the vibrations. I have also seen multiple ones for sale over the years due to people not liking the vibrations. There are several motor mounts no one complains about when it comes to vibration. CP-E is not one of them.

I had the cp-e on my first or 3 Fiesta ST's (back in 2016)
drove it for about 500 miles then removed it for the Mountune.
The cp-e is a great mount and we all know you prefer cp-e and Mountune parts. That's actually fine but it's a stiff mount regardless of preference. I've spoken to the owner of cp-e about making a street friendly or stage 1 mount as their Fiesta RMM is considered stage 2 which means "stiff" basically.
I've posted something like this before. It's merely my opinion and experience that the "firmness" scale is in the order below from most firm causing NVH off idle and or with AC on to least harsh, least amount of NVH. Don't get hung up on durometer numbers for each mount as some manufacturers have a different amount of leeway on their ratings and some are rubber (cp-e & Torque Solution) vs. Poly. Additionally, the different diameters of the large end and small end have an impact on NVH as well. We've used all the mounts listed below in our 2016, 2017, or 2018 Fiesta ST's.
1.) AWR 95a
2.) AWR 88a / revo
3.) AWR 70a / cp-e / Vudu / whoosh race
4.) Torque Solution / Mountune / whoosh street
5.) COBB

I have a Mountune, greased mercilessly, and it still creaks like crazy (but no perciptible increase in vibrations, which is a positive). I love everything else I bought from Mountune, but I am going back to stock until I figure out a better plan for the RMM. The stock 2018 RMM didn't feel much different, in my opinion, and it was totally silent.

comment was just funny🌈🌈🌈
The Whoosh is very similar to the Cobb but just a touch stiffer where the Cobb was a little too soft, you should be really happy with the Whoosh. I've been through a few and for the casual enthusiast who wants a very decent upgrade but not excessive vibes, the Whoosh Street version is the way to go... Now, I have an e50 tune that makes 300ft/lb of torque, so I I now have the Pwnall Performance RMM, that's a nice balance between street and race but it did take a good 2000 miles to really settle down to an acceptable level and I still feel some vibes from 2200-3000 RPM, so it's a compromise.
For 4 years and 2 FiST's I have been using the yellow street PowerFlex bushings in the RMM. I have since added the passenger and upper trans mount. The bushings broke in pretty quickly, but I was never happy with the vibes with the a/c on in the summer months. So I did an experiment. I bought a used RMM of e-bay 20 bucks and pressed out the small rubber factory bush. I replaced it with the yellow PowerFlex bush leaving the larger rubber factory bush. That was about a week ago and I'm very happy with the result. No vibes at all with the a/c, still have solid feel with clutch and gear changes and no wheel hop. No torque steer because in have a lower brace. I think I came out with a RMM that has the feel of the COBB mount for about 70 bucks. For some it may be to soft but for me its doing the job. I just didn't want to feel the vibes anymore.
I have the 70a and it is still too much NVH for MY liking, 1,600 miles later and the "feel" when pulling off the line. YMMV and I may put it up for sale. I bought a used Cobb, 3k miles, and it feels slightly too soft. so....Papa bear and Momma bear mounts are too hard and soft. Which one is for baby bear? Whoosh to the rescue?
But to answer your question: which one is the best? Answer: the one I don't have yet.
