What do you like best?
3ds max has a huge number of tools. The interface is clear and if you come from Autocad it is extremely easy to use it. Software most common features are very stable and even with not a latest pc it will work without crashing. Software has nice built-in tools but if they are not enough you can expand them with a pletora of free or commercial add-ons. It has an internal scripting language so that with a bit of practice it is possible to write own tools. In general it is the perfect software to be used for architectural 3d / rendering works or industrial design concepts and presentations. What i also like is the simplicity to create / modify materials and applying them with biult-in texturing tools.
By using it with a 3d mouse it be becomes even more powerfull.
What do you dislike?
Some features, like physical simulations or some add-ons may create stability issues.
It has a tons of animation tools ... but sometimes they are not so user friendly.
It has many features that are just a legacy from previous releases that noboy still use .... and that by being deleted could make the software going faster.
Last thing that i don't like is that, if you have a 4k screen, the interface can't be correctly displayed ... you may need to use 2017 release (if you can afford it) or interface will work correctly by having resolution of the screen fixed to 1920x1080 maximum.
