I was thinking the same, and since i swapped to gen2 w126 calipers and had the rears refurbished at two w123s i went with this set.
Goodridge Vint BL SS Brake Hoses fit Mercedes 200/300 (All Models) (W123) 76-85 | eBay
There is other manufacturers/brands, but i read good about these, and i got two sets, and my brother one set, my for w123, his for w201.
it looks good atleast some time (and obviously needs to be cleaned if you want them to shine bright)
But having stainless instead of things rusting felt good, and i imagined they are a bit more durable against external damage, wheelrubbing etc (that happened in the front when running wide tires)
So, ive got three sets from that seller, he have them in different colors aswell as braided non stainless for a bit cheaper.
i cant say that much regarding pedal feel, since i swapped both them and brakes at the same time, but cars with upgraded brakes, al aired out and those are a dream.
its painfully obvious to get back to a "stock" car later on.
ps, i drive my cars on track, or as on a track, so i felt it was justified
