lox vs o2 and tempature

[dragonstar57]

I was doing some research on the flame temperature if various fuels and a lot of them had temperatures for in air and also for in an oxygen environment. is it "better" to burn things using liquid oxygen or is it the same as long as you have enough oxygen? a 2/3rds h2 and 1/3rd o2 flame will burn at about 2700 Fahrenheit which isn't hot enough to turn steel into a liquid. would it be possible(or feasible) to have a liquid torch and would it burn hotter than the 2700 degrees for a perfect mixture of the gasses
*edit* my spell check plugin is a bit broken and it replaced temperature with tempature if someone could fix that for me that would be awesome!
