Can't go too much wrong with either choice. Both are good reputable bikes. The only problem with the Boardman is the Halfords store where you buy it from. If you can trust them, or have a Local Bike Shop that can do any work instead, then there should be no problems.
I bought mine off eBay totally unused. I got it home and gave it a good going over(I am used to fixing my motorbikes) and all is good with mine and I will continue to maintain it since it will make my life easier to do the higher miles rides.
