trek fuel ex9 2010 or specialized enduro elite 2006? THIS is the uestion

i have a trek fuel ex9 2010 but i want a biger rear travel and a sturdier frame. i can sell this frame and with the money buy a complete specialized enduro elite 2006. i will buy it for the frame.the components i have are ok. i am coming after a trek fuel ex 7 2007 crack and i am dissapointed. will the enduro be a more sturdier frame? or is in almost the same class? even the year is 2006 the bike is ex++ condition. i am 230lbs rider and i ride mainly singletracks,uphill,urban,forest (flat),trail,rare downhills at above 40km/h.
