Looking at the stats you've actually selected, what do you imagine they're telling you about these two players? Because a lot of the stats you've chosen to highlight seem either irrelevant or dicated by how much pressure a defence comes under rather than the abilities of the individual defender.
For example, here's how a similar comparison between Maguire and (taking a completely random example) Nottingham Forest's Willy Boly plays out:

Sell Maguire and buy Boly, apparently.
