Yes, they're an improvement for Priliyas and Dukes, don't know how you'd improve the Strom one though- the action isn't heavy, they're fairly reliable, they don't overheat etc. The only real fault is the grabby clutch, and I haven't heard of a replacement slave cyl as being a cure- I'm sure I would have heard about it if it was.....
I have some spare slave cylinders in good condition if you want.
But spare a couple of hours for bleeding it through, and get a decent sized bottle if fluid- it can be a bugger to bleed.
According to Alice, only women bleed, so suggest you get the wife/significant other to do it while you go to the pub.
Now, there's retro....

It's not falling off, it's an upgrade opportunity.
