From a functional point of view, other then the joy stick, the Vello is probably a good product, although I don't have any personal experience with it. However with regard to your last statement about it being "every bit as well built as the Canon.", keep in mind that the Canon BG-E16 grip is constructed of magnesium alloy like the camera body. The Vello is not, which is probably part of the reason for the higher price of the OEM version.
You're right, I had forgotten about the Canon being constructed with a magnesium frame like the Camera. I would like to revise my remarks to say that the fit and function (e.g. Feel of the buttons, etc) the Vello felt as solid as my Canon grip. I will say that had the Vello I first bought for my 7D Mark II had the joy stick to control AF points I would have kept it.
