Commuting on Airport Express MRT

Does anyone have experience commuting on airport express MRT line?

It’s definitely opened up Xinzhuang with Taipei and but does anyone use it much past Xinzhuang and out to the end to Zhongli

Wonder if anyone uses the “express” train to airport and then continues on to Zhongli.

Use Express to New Taipei Industrial Park/Chang Gung Memorial Hospital/ Airport and then switch to commuter to wherever your destination station.
