Liquid rockets usually use a propellant pair of fuel and oxidizer. I've seen some rockets from 1960's that used LOX/UDMH as propellant pair but why they are not used any more although it is mentioned that LOX/UDMH has higher performance than N2O4/UDMH but N2O4/ UDMH is used abundantly.
If there are any rockets with LOX/UDMH kindly mention them.

N2O4/UDMH is the choice if you need a non cryogenic storable hypergolic fuel. But UDMH is toxic and carcinogenic and should be avoided if possible. LOX/UDMH is not storable and not hypergolic.
There are a lot other fuels to be combined with LOX and they are not toxic or carcinogenic and thus easier to handle. There are combinations of LOX with higher performance than LOX/UDMH.

LOX/UDMH combines the worst of both worlds: the cooling infrastructure of cryogenic fuels, and the hazards of the storable hypergolics.
