IMO, composite doors offer the best of both worlds.
Remember that replacing external doors is notifyable if more than 50% (I think) glazed & any glazing in or adjacent to the door must be toughened safety glass; if in doubt phone your local authority for guidance.
Awe come on the expensive ones are expensive cos they are probably over rated & the cheap ones are cheap cos they are Carp.
JohnD would go for a "real wood" door & I would go for a "composite" door; get some prices, do your own "homework" & make up your own mind but probably £100 - £300.
