The d5 scatter is on another level, I'm surprised you think the tm one is better! The fidelity of the trees is also much better and more realistic in d5. TM is free now so in terms of cost it still wins and the path tracer is unmatched by d5. But for workflow d5 scatter wins.. Ps watched the whole video on x1.5 and didn't notice. Maybe you should plan your videos and be a bit faster with your presentation..
Generally I like d5 tools more , but Tm is more photorealistic. And also scatter tool is much more practical. d5 scatter tool is cumbersome and slow. main idea of the video :)
