yaesu 991a

So thing is fellas I just bought a new Yaesu FTM-500 dr I’ve been using as a vhf/uhf base, I usually use a Ft5dr and a comet sbb5 in the vehicle. My question is I’ve narrowed it down to a yaesu ft 710 or a 991a now I know I already have a vhg/uhf dedicated base but is the 710 worth the upgrade...
