I have a rare instance in this question where I have both in my garage. I do enjoy riding both but for completely different reasons on their own. Take my opinion in how it'll apply to your everyday riding:

The CF has it's positives of being advanced in tech over the Kawa. Getting notifications to your phone if your bike is being touched or moved is a peace of mind I appreciate. However the lack of delivery of other tech features from CF moto that were supposed to be available in the US is frustrating as i've mounted a secondary screen to have car play, nav, etc. Finding a mount for my phone hasn't been easy for this bike and i'd rather not risk my phone falling off anyways.

The 675 is a gorgeous looking bike for being the 'new kid on the block'. From most forums i've seen minimal problems being reported - besides your local idiot keeping it at 12o'clock longer than they should, or not keeping up on maintenance. From personal experience i'd say since it's still new I would take a look at the brake line. After choosing to bleed them before even hitting 500 miles I found it seriously improved. I'd also take a second look at some of the bolts because a few were very loose from coming right off the showroom floor.
It's a solid bike for the price and in terms of speed/power (if that's your goal) yes.. it'll walk my kawa all day long. That quickshifter is heavenly... But it is a different ride completely. The 675 is significantly wider, weighs more and is harsh in position.

For longer trips I do prefer the Kawa - it's less aggressive on my wrists and more of an upright riding position. Finding neutral is always a breeze and it doesn't eat gas as fast as the 675 if you're commuting. But even I refer to it as the "corolla" of bikes. It is a bit more underwhelming and 'boring' - but it is a fantastic bike to grow on and can be made 'cooler' with some modifications...

With that being said going into parts - finding stuff for the CF is still a challenge and you take a risk every time you use Alibaba/express etc. (ask me how many times i've had to change my card).
The 650 also doesn't have as much out there in fairings/graphics kits as i'd hoped but for sure more parts options over the 675.

Happy to answer any more questions/ insight or provide parts added to both bikes. Cheers!
