The Touring looks good to me as I'm really not fussed about heart rate, cadence, how many calories it thinks I've burnt or any of that nonsense - I just want to know where the fuck I'm going.
A GPS will tell you
where you are, and (if you're moving) which way you're headed, and how quickly.
None of that is map-dependent, but you can add a map into the mix, and it can be good, bad or indifferent. The GPS can interact with meta-data within a map to give you really useful information such as "Turn round, when possible."
OSM maps get mentioned a lot here, they are free and in my book they are 'indifferent' verging on 'good'. You can't argue with the value for money.
OS maps are also possible, but on a GPS they are expensive, and crap. Even if they are free (see Garmin Touring) the other still applies.
Garmin's own maps are expensive, and 'good'.
A mix of Garmin and OSM mapping is ideal, and easily achievable on a Garmin Touring model, I think.
