Although I find its cool that someone is doing something like that for Blender, the deformations are terrible (just look at those shoulders) and the anatomy is quite a bit off on all those models. I did try Manuel Bastion Lab, for a quick character its great, but if your aim is for realism, well, its simply doesn’t cut it. Its a good base mesh to sculpt off of for anybody new at it however, I wouldn’t use that for any project other then for quick testers, poses, or even as simple dummies to quickly block a project.
