you not see the image, only after long time small stripes on bottom, via a real Dr you see after seconds the full image. on teamrender you wait hours on big images until you see all.
on comparence to a real DR system it is quite slower also in total, i assume the TR system has more overhead, in the way maxon designed it.(being separate renders just stiched together in PV)
certain particle and motionblur things, randomisation tools/shaders, etc or other dynamic effects not work via TR without extra caching or baking. this is as c4d in effects splits the render in parts, using copies of the c4d file, not the original data on each node, and then composes this parts together in the PV. this kills many features, same as it does in c4d internal renderers.
TR also often decides to stop or never finish, on an 8 or 10k image this is very bad finding our after hours it wont finish ok. (see cg talk for the many errors users have with TR, in any renderer, this is not corona specific, so they also cant do much about it)
a real dr system, like corona render normally has natively, can add nodes while rendering and also release nodes without affecting the final result. you always get a good render.
a standalone system seems to use a lot less ram here and rendering faster than the renderer inside c4d. here we see almost the double ram with c4d than on a pure standalone.
we also miss corona features(in shaders p.e or volume features) that max corona has, to make corona only with thew limited c4d shaders, and not offering both we feel is a shortcoming, and artificial limitation, that hopefully will get overcome in future updates.
