Ground clearance and turning circle are the main concerns with a 675LT as an everyday car (even with lift). It is more involving, and hence more tiring to drive for longer distances (I am happy with this trait). It is always an occasion to drive the 675LT and it is amazing on the track (takes time to trust how fast and capable the car is). Coming from a DBS and an M6 you will need to recalibrate your driving for the increased speed. If you use it everyday it will affect the value in the long term, but would probably still be better than a 650S in terms of residuals. The 650S is a superb car and easier to live with, just that bit more comfortable and quieter. Its also less tiring to drive, but less fun. They are both not easy to get in and out of unless you're fairly agile. The doors are not ideal for parking, in both cars they need room to open and can get blocked by other cars. Seats are very subjective, so take a long test drive. I love buckets and find them comfortable, some people don't get on with buckets and prefer the sports seats, it depends on your size and shape. Finally the carrying capacity is limited to the front boot, about 150 litres with only a small central bin and small netting pouch inside the car, both are not easy to access when moving.
Unless you are a committed driver and do a few track days the 650S is a more rounded everyday supercar, with more than enough performance. I have not driven the 720S, but if you can afford the 675LT you should seriously consider it. It really is a 650S 2.0+. It is much easier to get in and out of due to monocage 2 and the new doors. It has extra storage for small things in the doors. The doors can still be opened in tighter spaces (they look really stunning), it has about an extra 210 litres of luggage capacity in the car like the 570GT. It is faster than the 675LT on paper. In the short term demand seems high so it should hold its value better than a 650S. It is a really fresh design and I think it will date well.
In summary, best everyday supercar 720S with extra wow factor and performance, slightly slower and less practical 650S, least practical and most effort to drive, but also most fun (wow factor to those who know) 675LT.
For me the best cars are about interaction/feedback, but as these increase so does noise (hopefully the right kind of noise), comfort decreases (you want feedback) and fatigue increases (interaction is tiring). This can be a problem some of the time in a daily driver, but for some its a compromise worth taking to enjoy a great car more often.
(Just to complicate things have you considered the 570S and 570GT? Recently drove both, they really punch above their price bracket. Its fun finding the right car/cars!)
