The things I like about my 2014 BMW 650 GT are the same things I liked about it when I first checked out the specs and read the reviews.
Like Old Scoot I too have been riding motorcycles since the mid 60's and therefore have owned numerous brands and models. Each seemed to have features I liked and didn't like. Therefore, I often said, "I wish I could put together a bike with only the features I like." A few important ones were: good handling, anti-lock brakes, a minimum 200 mi fuel range, 80 mph cruising ability, a neutral upright seating position, weighs between 450 lbs and 600 lbs, good gas mileage, a minimum of 60 hp, a rider adjustable windshield, the ability to stretch out my legs, good weather protection, cruise control, and, after having scooters and liking them around town, some kind of automatic transmission. The BMW C650 GT had all of those features except cruise control.
Therefore I now consider my BMW scooter as close to what I consider the perfect bike as I have ever owned (well at least for my age it is). However if BMW comes out with a future scooter with cruise control and some better GT color choices (that wouldn't be hard to do!), I may sell this one and then have the totally perfect bike.
PS, In So. California I couldn't care less about the heated grips and heated seat. What I would rather have is a cooling seat feature.
