Depends where you are, more specifically the condition of the lines. I used to live in Boston's suburbia and had Comcast/Xfinity as the only provider. Lines were old and very far away from their CO, so .. many issues. I opted for renting they $5 then $7 then $10 then $12/month cable modem so when I call for tech support they would not blame the problem on CPE.

Now I am in NYC and Spectum/TWC works great in my building (orders of magnitudes better than Comcast), I have the free cable modem but I opted out of the $5/month wi-fi and got myself a $55 ASUS AC1900 router (refurbished) and it worked just great!
