Any of the frames from the big names will be great. I like the look of them focus’s personally (dunno why). The Giant is no doubt awesome, but there’ll be little between the gooduns, going for the one that fits you best is probably your best bet.
My bro has an XL giant and he’s 6’4″. Its about the right size for him, but its to big for me at 6’2″. You may be best off trying one.
The Canyon Ultimate Al looks good aswell, decent frame, full SRAM force groupset, Mavic Ksyrium Elites and good finishing kit for your budget.
Another angle on it, I do all my riding in the lakes on a Genesis Equilibrium. Steel frame and forks so not mega light, but its dead comfy and descends very nicely. Ive built it up fairly light, got me round the Fred Whitton and up all the climbs without any fuss at the weekend.
