Verizon Fios Gigabit Connection is the better choice for users who prioritize reliable service, no data caps, and customer satisfaction, especially if it's available in their area. Xfinity X1 may be a more suitable option for users who need the absolute highest download speeds (in select areas) and are comfortable managing data usage and potential price increases after the promotional period, given its wider availability.
