Hypergolic fuels like dinitrogen tetroxide/hydrazene or monomethylhydrazine/unsymetrical dimethylhydrazine could be great if ignition systems were added for the rocket engines, those fuels are really toxic and volatile, but they generate a lot of ISP,don't boil off like LOX,LH and LHE, and combust when in contact with their respective oxidizer, thus making ignitions reliable and repeatable. i guess a good set of pros and cons for those fuels would be:
PROS: dense, HIGH ISP.
CONS: pricey, tendency for blowing up at the slightests impacts.

    That would be great, then we can build Proton and Ariane 4 without mods (mods don't work every time)

    Even LH2 has been proposed as NTR propellant, and consistent ignition could be insured by using electrical ignition systems @SyzygySoldier

    LOX can be prevented from boiling off by adding thermal control systems @SyzygySoldier
