Which one - polygon Xtrada 5.0 or Trek Marlin 7?

[The Rabs]

I'm just after some advice between these 2 bikes. I have no idea on which components are better on each bike, so I have no way of comparing the 2.

https://www.bicyclesonline.com.au/2018- ... ntain-bike – $699
https://www.trekbikes.com/au/en_AU/bike ... Code=black – $849 (but can get for $721 with Bupa discount).

The prices of them both are very similar – $22 difference. They're both close by, so can pick them up easy enough. I only do a bit of trail work, so narrowed it down to these 2 bikes in my price range, but I have no idea which is better. Can anyone help me decide between the 2 pls?

it's interesting that in the comparison on Bicycles online site, they compare their bike with a higher priced Trek bike. The Trek wins on 2 counts only but is $500 more expensive.
Both these bike have hydraulic disc brakes which the earlier marlins did not have.
My friend has a Marlin and I find it a bit heavy to ride.
Good luck with the purchase.
