Feor had great timing, movement and distancing. Fedor loved the Russian hooks which although not that technical served as a way to enter the clinch. That Feint punching and his hand trapping works well, which is why he outstruck Cro Cop who was a more technical striker.
Wand also has very good timing and an understanding of Muay Thai beyond what he's able to do. This is evident on his fight against Jardine who used the same low kick that beat Chuck. The difference is that Wand was able to counter it and KO Jardine. The reason for Chute Boxe looping/brawling style is because that's how they learned how to fight. They brawled and never got any better at it. Here's a very good counter to a lazy low kick. Horrible looking technique but good timing.
Shogun is actually a very decent striker who has a better understanding and application of Muay Thai than Wanderlei. He had good head movement and great kicks that served as a way to control the distance. His looping punches were also a product of his brawling. He did get better at it thought. The best Shogun is the one that beat Chuck and Machida. Unfortunately that lasted very little. Here's some very good head movement and a kick to stop Chuck's momentum rather than just running back.
Those three guys are way better strikers than Cat, Miesha, Eye, McMann. They also have a better understanding of distance and timing so they don't get caught as much. There's control in their chaos, specially in Fedor's case.
Ronda was submitting a bunch of Blue belts and outstriking non strikers. Cat has horrible striking and is one of those I beat a fat Thai so I'm good at Muay Thai strikers (I call it the Master Tody approach). Cat's punches are horrendous, her knees are strong but lack technique.
This is a bad habit many people pick up in Muay Thai until it is corrected. You bring down both hands to knee. That's how Nunes almost knocked her out.
Sara McMann for some weird reason regressed in her striking since the Ronda fight. She was at her best against Ronda. However, Sara lacks proper defense and drops to turtle when she gets hurt. Which is why she gets finished a lot. Her wrestling is top notch though.
Bethe is a blue belt on Wallid Ismail and lacks boxing ability. Throws arm punches and is not aiming just wildly swinging.
Alexis Davis is probably her biggest win in terms of credentials.
Jessica Eye lacks ground game and is horrible at striking just like the rest of the division. Chin up and flailing about.
Liz was also a blue belt when they fought, maybe a purple but I doubt it.
I forgot the rest of the people in that division.The most important thing is though that most of those girls would be at 125lbs if that was an option.
I personally think Ronda is great for MMA and Pro Wreslting, which are two things I enjoy. However, she has not faced top competition. That's not her fault though, because there is no top competition is Women's MMA. She and Cyborg are on the same boat, beating the crap out of people who aren't good enough.
Edit: Notice how you had to go down 2 weight classes to find a decent WMMA striker...
