Sage one v Xero for small retailer

Hi

Just looking for opinions from people that have used both packages. I will be taking over a small retailer and have an accountant for vat returns etc but will be learning most of the day to day things myself. Both of these packages have an app that links to our Epos system for real time uploading etc but the Xero app has a cost and sage one does not

Could anyone recommend either of these in terms of ease of use, functionality etc. Or is it really a case of both do the same and people just like what they are used to?

thanks
