Monroe is for buicks, lincolns, cadillacs, and other land-yachts where ride comfort is #1 and handling is irrelevant.

Bilstein HD's are of a FAR better construction than the Bilstein TC's. You don't want the TC's. The HD's are very high quality and will last many years. They are also very slightly more firm than OEM, giving you better high speed stability and sharper cornering.

I believe Sachs/Boge is OEM. I'm not that impressed with them, they don't seem to last nearly as long as the Bilstein HD's.

You want all FOUR of your shock absorbers to have the correct valving for compression and rebound. Mixing brands is a bad idea unless you have the compression and rebound numbers for both brands and can verify that they are identical. Compression and rebound specs can vary wildly between brands and between models, and mixing them can result in a car that handles quite bizarrely.
