Really - the two options are great options and I have tried both. The other option I have tried is the homebridge for hubitat app too.
HubConnect adds a lot of functionality and if you have multiple hubs alongside hubitat (like smarthings which many do) is probably the best option.
I prefer HOOBS/MakerAPI option as it is the fastest integration. It is nearly instant with a small footprint. MakerAPI is a Hubitat focused tool and is solid. Now that hubitat is my only hub (other than my apple tv homekit), I'm focused on stability and speed. As I have been a former smarthings, wink, and homeassistant....I have moved towards one 'brain' which is hubitat and one 'ui' which is homekit.
