The TL doesnt have the same class and over size as the RLX would, the RLX has more luxury its almost like saying why buy a 3 series over a 5, i mean its the same everything is just bigger with extra features here and there.
As where a TL is classed as a sport luxury where as the RLX will be classed at a Full sized luxury sedan where as the TL is still a mid sized sedan
