From my experience, different levels of Layer-3 support is common across many manufacturers, for their more price-sensitive product lines (there's a reason why they cost less). That tends to fall in much the same way; starts with routing between directly connected VLANs + static routes, probably with a limited number of routes - then adds features & capacity (and usually complexity!) as the cost of the models goes up.
I think attention to detail, in reviewing available documentation, in advance of purchase, is definitely recommended, regardless of manufacturer. Layer-3 is just one of those blanket terms that covers a variety of actual technologies. if you specifically want any of those technologies, best to check they're supported, up-front.
