Virgin Home Internet is FTTN service, not FTTH. Even both FTTN and FTTH is available at your location, it will use FTTN anyway - this happened to me. I have heard if your address has FTTH only, you cannot install Virgin.
Once you are on the internet, your IP is gonna be Bell Canada IP address, sometimes the IP appears to be owned by Virgin Mobile Canada. But IP address range is the same as Bell Canada. This means you are on a Tier 1 network. Even other service provider may have cheaper price, their backbone network gateway may impact your internet experience. For me, I don't notice any difference between Bell Canada and Virgin Mobile Canada in terms of network experience.
Multiple speed test results that almost at all time it is 25/10. Only once I got 14/10, called Tech Support (Bell agent picked up the call), was instructed to reboot the modem Steve (re-branded refurbished Home Hub 2000 from Bell, certain feature been disabled such as IPTV etc) and it went back to the expected speed.
So far my experience was good with Virgin. I am happy that I made this switch. Although I miss my FTTH service, at lease I don't need to beg Bell Loyalty anymore!
