As for which ones to use, this is really a personal preference down to what you class as "better". Virgin's DNS should be the fastest but you're talking differences in terms of maybe 10ms per query and the reality is that the router itself (or the PC) will cache queries so you likely won't see a huge impact no matter who's DNS you use.
The advantages of using an alternative DNS are things like stability (Virgin's have gone down in the past) and even control - if you use OpenDNS, you can specify things like parental controls or even get some nice statistics from your network.
I, personally, use a mixture of OpenDNS and Google DNS. My Primary DNS is 208.67.220.220 (OpenDNS 1) and my secondary DNS is Google (8.8.8.8) - the advantage of this is that if OpenDNS ever goes down, Google shouldn't be affected. I've not had a DNS related issue in about 4 years now. There's nothing stopping you using Virgin's DNS as your primary (194.168.4.100) and maybe Google as your secondary, so you theoretically get the best of both worlds.
