Definitely go B6. B4 is basically stock. B6 is performance improvement but like, balanced. OEM+ performance improvement while retaining comfort.
Pros: performance improvement, balanced, comfort

Get bilstein B4 OE shocks. Decent price and will ride like stock.
Pros: decent price, rides like stock
Vehicle:
Volkswagen Golf
I like my Bilstien B8's, made for lowered cars.
Pros: made for lowered cars
I put Bilstein b6 on mine but you’d have to probably do the front too if not going with OEM stuff. I also put 034 mounts which are fine on the front but I’m about to go back to stock on the back due to noise.
Pros: fine on the front
Cons: noise on the back
Vehicle:
Volkswagen Golf
my e91 has bilstein B6 with stock springs and it rides great.
Pros: great ride quality
Vehicle:
BMW
I installed stock(unmodified) Bilstein B4 shocks/struts on my 2017 REX with 19” wheels and the improvement was noticeable. Overall the ride was less unsettled and bouncy.
Pros: ride less unsettled, bouncy
Vehicle:
BMW
Switched to Bilstein 5100 and have always had them in the rear. I’m mostly pavement unfortunately and it’s been great
Pros: it's been great
I decided to swap in the Bilstein 5100s, gotta say they ride a lot nicer when the truck is empty--We'll see how they do with a gear load on the next road trip.
Pros: ride a lot nicer
Mileage: 30000 km
Note 5100s are not soak up the bumps kind of shocks. Depending on what you think is atrocious about your current ride, it might not be an improvement. My 08 V8 feels stiffer/sharper on bumps compared to OEM shocks, though it handles them with better composure, less resonance/vibration on hard hits, and handles washboard and bumps better. Also less body roll.
Pros: better composure, less body roll
Cons: stiffer/sharper on bumps
I can relate. My B16's made strange noises from day 1. Then after a few months one of the rears collapsed. I gave up and just put the original stock shocks/springs back on.
Cons: strange noises, rear collapsed
Vehicle:
Volkswagen Golf
