BLender is a god send to those who are poor/middle class/not loaded or in school, but the caveat having said that IS:
Sculpting is terrible, inflate doesnt’ always work right, and the sculpting brush does NOT conform to the surface being sculpted, dead end right there.
Edit mode in blender is very slow, and the reason is OLD gl code, and that won’t change until they can hire new coders that left to work for big companies, and find a way to find time, to change all that code into newer GL . Until then , People like me and even people ( Check blenderartists forums, its all there) that have i7’s and gtx 970’s, have sluggish 3d viewports on models where maya and rotate freely .
If you have models, or plan on it, that have small to medium triangles, blender would prob. be fine.
Maya and 3ds have features blender can’t even dream of atm, and blender I think at least, has a few they don’t.
You would need to do huge research to verify those things, using the exact same models throughout.
What I"ve said though is fact, verifiable on all blender forums, and they’ve been ‘known’ issues for a long time now, with no fix in sight because many devs left for high paying jobs, unless they have since filled them and haven’t had time to fix the issues I"ve noted.
Due to the horrible sculpting, I use meshmixer instead, you simply can’t beat meshmixer for sculpting, and I say its MILES above even zbrush because of the viewport handling alone. Its a tough app to beat, no doubt in part, because who is behind it ? Autodesk. Did I mention it’s FREE ;_
All of that, is from personal experience, and if we could share a computer connection, I could prove all of it to you right now.
I will reiterate, for what blender is, using small > med.ISH models its a heck of a deal for free for what you get, but its got a lot of problems right now.
That should help you make a decision.
IF it were me, and I had access to 3ds or maya ( especially now with LT allowing unrestricted poly counts on export -2016-), and could afford it, I"d be all over either app depending on what I needed done. Maya/LT tends to be used for film and effects and I think for architecture and games, except now for LT which supposedly has streamlined that for games.
Autodesk will tell you what the difference is, check their website , as I’m not 100% sure on that info.
