The IMX335 can do well at night; it's in the A119V3, the A139, and the B2K so you can check vids of those cams to see it's potential. The IMX291 is better at night, but has a lower native resolution so it's not as good daytime. No experience with the Toguard but on the cheaper side my B2K is a great value and for a little more the A119V3 is a very good cam and an excellent value.
Every cam is a compromise so choose based on what you need most. I do very little driving at night, and US plates are tough to capture, so I tend toward best daytime performance as long as night performance is decent. No matter which cam, the odds are that save for the closest cars I won't get plates at night but the UK plates are far more readable so this approach may be good enough for you too.
