GTS isn't so great 2-up. Beverly is much more comfortable for longer distance with 2.
My wife rides her own scoot (Yamaha Xmax 300); rare that she rides on the back of my Vespa... generally, if we are getting one of the bikes serviced. On those rare occasions, she is not a fan of riding pillion on the GTS: the passenger pegs force the legs out, then in. Her toes whack my heels. The aftermarket passenger peg extensions would be a necessity if we were riding two-up with any regularity.
Be sure to try out, if you can get a ride on one of the used ones (a lot of dealers won't let you test ride a new Vespa)... see how you fit two-up. I also agree that the HPE feels stronger than the previous models. I was perfectly happy with my 2009 GTS, but my wife was encouraging me to update (maybe guilt after she got the Xmax). A significant difference when I got a 2020 GTS HPE.
All that said, if you go with a used GTS, you can get into it for for less money (obviously)... you won't know what you're missing if you don't ride an HPE. If I was looking to do regular two-up, I would give a second look to the BV or the Xmax.
