Diamond Back M20 or Giant Rincon

Hi there, can anyone tell me anything about the Diamond Back M20. i.e if you own one or know someone who does and what you think of it. Same with Rincon.

Both these bikes are the same price £250.

Is it basically just a matter of preference between Diamond Back and Giant as the specs are pretty similar.
Or is one generally a better make than the other.

i can't decide what to buy
Cheers

If the specs are that similar and the bikes are both well known brands (they are) then choose the one you like the look of.
