I believe in terms of numbers the most popular is still Chamberlain. Their web app is called MyQ. There is an unofficial integration between MyQ and SmartThings
With regard to alternatives, the linear that you listed (which is also sold under the go control, Iris, and Nutone brands) and another brand, Telgard, both meet UL safety requirements and work well with SmartThings.
The WeMo and other relay options essentially just hotwire the garage door controller, and do not meet those safety standards for remote operation.
Whether you care about that or not is a personal decision, but it would be important if you want to use the device on a rental property, or even an Airbnb location.
The Linear is the only one with an official SmartThings integration, and is very popular in the community.
