[FIOS] Move from Comcast Blast Worth It?

I have Comcast Blast 200mbps at my home. But rarely get 200 as my download speed. It's mostly 50-60mbps that I get. Is it true that frontier fios has consistent speeds? I mean if I get 100/100 plan will I actually get 100/100, at any hour of the day? Also I see that Verizon Fios is currently ranked number one ISP in the country. Is frontier comparable to Verizon since it's the same network but a different brand?
