I agree with Daxel: I don't think you'll find Adobe Animate easier to use than Moho. At my workplace, I use Moho, Adobe Animate, and Harmony, and to me, Moho is by far the easiest and fastest way to rig and animate 2D puppets. However, the other two programs are more robust for
frame-by-frame animation, so it really comes down to the type of animation you want to create: poseable puppets or drawn FBF.
I mostly work with 2D puppets with some FBF elements, so the choice is clear for me.
I will say that
Moho Debut has many limitations compared to Moho Pro, which could make it harder to use for certain types of animation. Before you move on, you might want to install the trial version of
Moho Pro to see if this version meets your needs/expectations. If Moho Pro works better for you and you're looking to save money, I would take advantage of the Black Friday sale going on right now. But first, see if LM will refund your Debut purchase or give you credit towards the Pro purchase.
For FBF animation, I like using Adobe Animate but be aware that Adobe's pricing structure can make it a lot more expensive than Moho. IMO, an Adobe CC subscription is only worth it if you use several of their programs regularly (which I do.) Also, while Adobe Animate does feature rigging tools, they're not as advanced as Moho's. For example, there's no equivalent in Animate for Moho's Smart Bones or Mesh Warp system. I also use Harmony at my workplace, which has FBF tools and puppet rigging tools, but I don't use Harmony in my personal work because it's too expensive for me, and I think Moho Pro is easier and faster for rigging and animating 2D puppet setups. I also like using TV Paint for FBF in my personal work, but this program is not used for puppet animation at all.
That said, with the recent Freehand tool improvements in Moho 14, I've started using Moho to draw 'simple' FBF sequences and elements and will probably use Adobe Animate less now, especially as Lost Marble keeps improving FBF for Moho. Traditionally, FBF hasn't been one of Moho's strong areas, but it's gotten better and more usable lately. I may still use a dedicated FBF program for more complex FBF tasks, but that's actually a rarity for me.
I hope this helps.
