Since you got my attention, and I'm retired and have the time, I went down to my local Nissan dealer, just a few miles from my home, to check out the Versa Note SV HB.
In summary, the only thing I liked about it over my 2009 Versa SL HB was the exterior styling, larger behind the rear seats cargo space (21.4 cubic feet compared to 17.8), and the estimated (doubt if you will get it) 31 city/40 hwy mpg with the CVT, old Versa estimated 27/33MPG. I get about 29 MPG combined. The Note is 200 lbs lighter.
They both have ample rear legroom.
From 0-60 mph I thought my Versa, 122HP, 1.8 L engine, is slow, 9.1 sec, but the Note, 109HP, 1.6L, at 10.8 sec is just a bit quicker than my lawn tractor. On the positive side the Note though is quieter.
They both handle just ok. These are not sports cars.
I do like the exterior styling over mine, except the SV comes with plastic wheel covers, at least mine came with alloy wheels. I hate plastic wheel covers.
The interior is almost all solid cheap plastic, even the left armrest. One of the main reasons I purchased my Versa was the upgraded interior compared to the competition.

So would I trade my Versa in for a Note. Don't think so. Why trade in your car if it's running fine. If you are looking for something in this category also check out the Hyundai Accent HB.
