Ragley Blue Pig - Most "allround" IMO, of the "hardcore hardtails", along with th one one 456. Long chainstays, not very compact, more of a typical steel, trail hardtail on 'roids. Dialled PA would go here too.
NS core/Surge (I have a surge 2, reet loads of fun, my BMXers body can cope with 3+ hour rides on it pretty easily too). Short chainstay (which is also adjustable, so SS compatible), not too slack seat angle (so good for putting the saddle up), no doubt harshest riding, very compact, an all round bike as far as a BMXer/DJer/Downhiller is concerned. Very playful due to being compact and short chainstays.
The NS core bikes are pretty much the only off the shelf complete hardcore hardtails. 160mm forks, dual ring, short stem, wide bear, big tyres, etc, etc.
Charge Blender, much like the NS surge, not quite as playful, but has a slack seat angle which can make seat up climbing a problem.
Cotic BFe best of both extremes IMO. More capable of day rides than the surge and blender, but not as capable as a pig. less playful than the blender and surge but more playful than the pig.
What do you want out of this bike? All day rides and bouldering over stuff or playful couple of hour rides with a more exciting bike underneath you?
