Subwoofer Out VS Subwoofer Crossover

I have been running a sub for many years now. I string the speaker cables to the sub and then out of the sub to the speakers. The sub maintains a crossover dial/adjuster. I’m now buying a new integrated amp (Yamaha 701). It has a dedicated rca sub out channel. If I use the sub out, I won’t have a crossover control. Should a still string the speaker outs to the sub and ignore the sub out if I want crossover control? Is one better than the other. I like my crossover control.

Thank you.
