Best tyres 235/55 R17

[we44]

Time to renew the tyres on my Phaeton (2011).
I've got Kumho Ecsta HS51's on the front and Dunlop SP SportMaxx TT's on the rear. It's the rears that need replacing.
I'm tempted to fit the Kumho's throughout (I replaced the Dunlops with these about 8 months ago), but the Dunlops were the "factory fit".
Any advice / recommendations for other options people have used?
235/55 R17 tyre size.
BlackCircles have both at a similar price point.
Also tempted by Yokohama Advan ST V802's as designed for 4x4 and SUV's i.e. heavy cars.
Thoughts?

Kumho is a swear word and my dads sidewalls split in a life threatening way and he wasn't alone.
