Which hardtail out of this lot?

Hi fellas, its spot the noob time.... 
Work is takin part in a cycle to work scheme, and it seems as good a time as any to upgrade my 15 year old Claud Butler Xanthia

Its got to be through Wheelies direct and ive narrowed it down to these:
Genesis Altitude 00 2009 http://www.wheelies.co.uk/products-Alti ... _21624.htm steel :?:
Scott Aspect 20 2009 http://www.wheelies.co.uk/products-Aspe ... _19388.htm let down by the suntour forks? I've ridden this one....very nice!
CANNONDALE F4 2008 http://www.wheelies.co.uk/products-F4-2008_13610.htm what are the forks on these like?
Specialized Rockhopper Comp Disc 2009 http://www.wheelies.co.uk/products-Rock ... _21750.htm my personal favourite, upgradeable frame?
Giant XTC 3 2009 http://www.wheelies.co.uk/products-XTC-3-2009_20263.htm my m8 has an xtc3.5 and he loves it, seems well specced too
Alll in all im gonna get a good bike for £700ish surely, just hoping some of you knowledgeable fellas may push me in th right direction
im gonna try and get out and test all these bikes of course
many thanks in advance

the scots have short top tubes ....the giants are longer..
sorry try them first and then come back with a short list of what suits.

All the bikes are pretty good value - the Scott having a budget fork though (its good, but the Toras are much better).
The steel framed bike may give a softer ride, but will be heavier.
