Saab Viggen, Mirage F1, Mig-23 and Phantom : who is (was ?) the better? ?

Four superb jets of the 60’s :
– Mirage F1
– F-4 Phantom
– Saab Viggen
– Mig-23
Who is the better ? Twin-engined, but heavy phantom ? single-engined powerful Viggen and Mig-23 ? or slightly underpowered but nimble Mirage F1?
I open the debate… 😉 😀 😀 😀
