I have a 20W X 16H and a 40W X 14H Hi Fold. Performance has been very good. I had one gear seal go out but since that door is in a heated shop and is insulated, I replaced the oil with grease.
One main reason I went with Hi Fold is one doesn't lose any headroom, as one does with many other bi-fold doors. That is the reason for the extension legs.
Shipping can be a factor in final door price.
In snow country, I didn't like the idea of a hydraulic door having to swing out and thus have to clear snow away first. With the bi-fold, as long as the bottom seal isn't frozen down it lets one open the door and then broom the snow away as needed.
With any of these doors, one wants to consider the load bearing weight. By the time one adds windows, insulation and the metal sheeting the door may be rather heavier than one thinks and they have an engineered weight limit.
I installed the smaller door years ago with my 16 year old daughter's help using a farm tractor and loader bucket. The bigger one I installed this year and hired out because I'm older now, but it was just as easy and straightforward to get it plumb and true.
