I moved from a Burgman 650 ( terrific bike = put 100,000 kmn on a pair of them - also with a DayLong) to a 2010 Wee specifically for long distance touring with my son.
Couple of reasons
was primary ...as you know it's terrible on the rear tire on the Burgman - I was doing 10-12,000 km ride and did NOT want to do a tire change.
....the Burgman is decent but there are so many farkles for the Wee as far as luggage goes - loaded for 3 weeks on the road with the kid ..I had to carry for two pretty much ....spare fuel etc. Dubbed it the Mule.
Put 15,000 km on the K60 Scouts and it easily passed safety when I sold it ( then bought another ).
....much better on Wee...I was getting my teeth hammered on The James Bay Road while buddy on the strom was floating over them.
Range on a single tank
....Wee is much better 400 + km
Any dirt road travel the Wee is superior
and has much wider range of tires available.
Performance and handling are on par
...the Burgman brakes and lights a bit better.
Top speed on the Wee is higher
the Burgman is superior.
Forget about that Honda 7xx series
..motors are horrors ...6200 rpm redline. Just dull and boring. Kid and I tried them and both of us had nothing good to say.
The CB500x tho is a contender for you.

Brilliant bike. One of the best demo rides I've had
It held up well against the Wee and is just plain fun to ride
and a huge and growing market of farkles.
You are the same height as me but I only have 30" inseam so needed some altering to be comfortable on a heavily loaded Strom...they tend to top heavy when you add a full tank, tank bag etc. There are lots of lowering options and seats.
Strom and CB500x benefit from fork braces and better forks/springs on the Wee are a big gain to manage that longer suspension.
Two up tho the extra size and power of the Wee might be useful and there are a lot of well farkled bikes out there for reasonable prices.
