This is very relative, no serious studies have been done about it.
They are both on the highest food chain and from the same family; Tigris-tigris and leo-tigris, so biologically speaking they will have the same natural life span as tigers and lions and will have the ability to survive in the wild under desert conditions or in the jungle, they will hunt some of the biggest prays in the wild.
This is my own assessments based on biology of the animal kingdom, there might be other circumstances and variables to take into account.
Differences already exist, depending on whether it is an offspring of a male lion with a female tigress (Liger) or a male tiger with a female lioness (Tiler).
If we look at the interbreeding between Dog races we can see that it is possible that Ligers can survive as much as Lions and tigers.
Hope you understand my analogy now.
