Garmin considered slightly more accurate than Tomtom?

[Merc]

Is it generally considered the Garmin maps and directions are slightly more accurate and upto date than the TomToms map provider?
I've seen a few posts/statements which seem to suggest this. Agree/Disagree?

In Ireland this is definately the case. No idea if its the same in Britain.

I found the Garmin is slightly more accurate when using postcode/building number directions - e.g. TT sent me to the other end of my cul-de-sac, Garmin took me to the end of my driveway.

Garmin use a different source for their maps from TomTom. In general, Garmin maps tend to to be more up-to-date and accurate. See here for some feedback on the differences between the Nuvi 360 and TomTom 910 ...

... the Garmin maps (NAVTEQ) are generally accepted as more reliable than TomTom (Tele Atlas). ...

I took the plunge and went for the Nuvi 360.

I’ve had the Nuvi about a week now so have given it the briefest of tests, but here’s my initial opinions anyway.

The maps - vast improvement on the TomTom (from a UK point of view). Much more accurate and up to date with more detail.

Sat-Signal - faster acquisition of satellites and more reliable (I havent lost signal once yet in my travels (TomTom used to regularly lose signal)

Size - I was never bothered about size originally but the Nuvi being so small is a real bonus. It looks very neat in my car and is easy to remove and slip in a back pocket. In its provided case it looks like you’re carrying a wallet.
