I'm new to CT, had AT&T fiber in previous state and Comcast fiber before that, and had Frontier installed here when I moved in last summer. It works exactly like any fiber internet, but costs less. I have had 0 issues with it.

Not to mention: Comcast charges you if your monthly usage is over 1TB; the other companies do not. Unlimited Fiber thru Frontier is cheaper than capped-at-1TB fiber from Comcast.

I'm also of the opinion that anything that can get you off Comcast is a huge win..
