This can easily get like an oil thread as it is very much personal preference. For my opinion, if you want smooth go with the non-sport bilstein shocks.
Of course it depends somewhat on what else you've got back there like the spring and what shape it's in, and what's up front like bb or not, but generally the Bilstein HDs would improve your ride.
Any gas shock is an improvement over all-hydraulic shocks. Monroe-matics or Delco gas shocks are OK and the ride will be much smoother. Bilstein Heavy Duty shocks are much more expensive, but will last 5 times as long (if you plan on keeping the car that long). Bilstein Sport shocks will be firmer and not what you want.
Bilstein Sports if you have a higher rate fiberglass monospring. The ride is still smooth - TRUTH!
Bilstein HD if you have a steel spring or a soft fiberglass monospring.
Fiberglass springs require better shocks without question. Try a monospring without better shocks and you will experience the bouncy rear syndrome. Difference is like night and day once you get the shocks right.

My 1968 SB car has a new stock style 9 leaf rear spring and new AC Delco shocks all the way around. Seems fine to me as I like a softer ride for touring.

As said above, everyone has an opinion. I have a shortened 360 lb glass spring that brings it up to about 380 lb with Bilstein Sports and I think it rides very good. Up front I have shortened 550 spring also with Bilstein Sports.
I ran the Sports on my 80 Vette with the stock F41 springs and it rode good too.

Bilstein HD's with a VanSteel 330 glass monoleaf on mine - The ride is smooth, yet firm, not bone-jarring at all. As already pointed out, the shocks won't do anything for you if the spring is in poor condition. Prior to my change-out I had the original old rusty multi-leaf and tried some OEM Delco shocks and it was like riding on a 2x6. At times I wish I'd gone stiffer than the 330, so definitely would not go softer.
