I will add on top of what Scott said, i think people are mainly complaining about the modeling workflow more than the tools themselves.
I personally find the modeling workflow in cinema very slow not really efficient.
Back in days, i used a lot cinema mainly for the mograph module and the text tool.
But these days honestly nothing much left for cinema, now that maya is having Mash wich i found much more powerful, you can use it the easy way with the mash editor or digging in the nodes and wire things like you want and even combine them with soup.
So at the end you have a very expensive package that doesnt do that much very well.
As you said UV sucks really, modeling tools will do the job but slow workflow in general,
add to this if you want fluids and particle you will just have to get TFD and Xparticles so you can add to this the price of these two plugin.
That being said the strongest point of C4D is the ease of use.
I have some friends (graphic designers) and when they ask me what soft they should use to start 3d and include 3d text etc on their work i always recommend C4D
