Frontier vs Optimum in Darien
Darien’s trade-off is Optimum’s broader, cheaper cable service versus Frontier’s fiber with symmetrical uploads where available.
Optimum is the better overall pick because it reaches more of Darien, posts the stronger speed score, and starts at a lower price. Optimum wins on coverage, overall performance, and price, while Frontier wins on fiber’s symmetrical upload potential where available. Optimum is right for households wanting broad availability and the best all-around value; Frontier suits users who prioritize fiber uploads and can get its service at their address.

Rank score (0–100) is each provider’s Speed Score, discounted for weak upload, times the share of that ZIP it reaches — the same rule that orders providers on the Darien city page, so it moves as availability changes street to street.
