I'd say it is all about the comfort of both you and your passenger, but I cannot comment on pillion carrying on my SH350 nor the Forza. Though I don't doubt that they'd cope 2 up.
Scootabout's last post on your '..which scoot for 2 up...?' thread is good info IMO, and other's posts about testing etc are enlightening.
I can only add a few comments on my very new SH350 that may help you:-
It may be 'tiny' as Mr G stated, and it is smaller relative to bigger scoots but, it is still a physically larger bike. It immediately made my Nmax 125 feel compact and claustrophobic. I'm 5'11, so not tall at all, and it is a very roomy and comfy scoot, notwithstanding the fact that you do have limited foot room and less ability to move around on that comfy seat with a pillion sat behind you.
It is lighter than most scoots in its class I'd say.
The smoothness of the motor with updated power and torque is an unexpected revelation from Honda, I read that they have added a balancer for 2021.
So, you'll have to sit on a few, move them around a little on the showroom floor, test ride a few, then go for a HONDA in any guise!!
