It’s a fully capable modeling program, but a lot of artists don’t like the workflow, tools, hotkeys, UI, etc, compared to 3ds Max, Maya, or even Modo. Some of those opinions are dated first impressions, some of people feel like blender controls are too different with no benefits from being different. A lot of tools in features that are built into other programs are add ons and plug ins with Blender, which can be a good or bad thing.
Modo is worth checking out if you want a cheaper alternative to Max or Maya, and there is an indie version.
Blender does suffer a bit from most professionals use Max or Maya, so most jobs/tutorials/guides/etc are all for Max and Maya.
