The animation team I'm with at
DreamWorks Animation uses Moho in various
TV productions. In the past, it's been used for
Puss In Boots, The Croods, and
All Hail King Julien. I have some examples on my 2017 demo reel. To be clear, the team I'm on uses a lot of different programs for animation production, but Moho is used more routinely in a lot of our recent work. IMO, the work we do in Moho nowadays is looking more sophisticated and I can't wait for the release.
Cartoon Saloon also uses Moho for their TV productions and also for parts of their feature films. Check out
Puffin Rock on Netflix and
The Breadwinner feature trailer for some recent examples.
I don't know about Moho at other major animation production studios. They may have pockets of artists using it. Moho is probably used more by smaller studios.
As for other software, Toon Boom Harmony and Adobe Animate (formerly Flash) are commonly used in American production. I think RETAS is used a lot in Japan, and TV Paint is popular in Europe.
I work with many animation programs myself (most of the above and then some,) and can say they all have their strengths and weaknesses. The program you choose should depend on your preferred style of animation and designs. And, certainly, there is no reason to limit yourself to a single program. Most of my 2D work at DWA is a combination of Moho, After Effects, and occasionally LightWave 3D. Last year, I did a segment of The Croods that also merged in characters I animated in Toon Boom Harmony. I also use Photoshop and Illustrator to create elements for animation.
I personally prefer Moho over Harmony for rigged/puppet style animation. Moho's rigging system is more capable with full IK and true targeting support, and it has Smart Bone Actions which are kinda like Set Driven Keys used in many 3D programs. The Layer Comp system is a huge timesaver for compositing, which I rely on heavily.
Moho's one arguable weakness is its drawing tools, which are designed for creating optimal shapes for deformation. Moho's drawing process can produce very high quality but it does take more time and thought to create the shapes than simply drawing what you need freehanded. I think this 'click and drag' method is what keep more traditional artists from immediately warming up to the program. Most artist just want to draw what they need without thinking too much about it. To me, drawing in Moho is similar to modeling objects in a 3D animation program, which is fine for generalists like me who also work in 3D, but for some elements I wish I could just draw quickly and be done with it. Moho does have two freehand drawing tools but they're a bit buggy and unreliable, making the program less suitable for FBF style animations. Hopefully, Moho's drawing tools will get a makeover in the next big release.
For freehand drawing, Toon Boom's are better, and the program is better suited for FBF style animations. Even for puppet style animations, it's nice to be able to draw directly in the program with vector or bitmap brushes, and not waste time fixing point and curve errors. (Besides better freehand vector tools, Moho really needs to get some basic bitmap painting tools too.)
At home, I recently upgraded my old TV Paint license and I"m really enjoying using this program for FBF. TV paint is mainly a bit map animation program but it's very fluid and intuitive. I'm also experimenting with a newer program called CACani, which is a vector based 2D animation program that has some unique interpolation capabilities. Neither of these are suitable for puppet style but the output can be combined with a program like Moho.
I haven't used RETAS but I do use ClipStudio Paint for my comics work, and that program has a tiny bit of RETAS' animation capabilities now. I haven't tried animating in CSP though.
Getting back to puppet style, After Effects is actually quite capable too. When you add the DuIK plugin, you get some similar capabilities to Moho, plus the use of AE's many excellent FX tools. My favorite AE features for animation is Liquify and Puppet, both of with I sometimes apply to Moho output I import to AE. For puppet animation, it's a bit clunky compared to Moho, but within limits, you can still do nice work with it. (Some of our early Croods animations were done using AE and DuIK.)
I wish I had the best of all of these programs in one package. Till then, I"m glad I"m not limited to using only just one.
