There's a fair amount of RD tech out there with clutches and oversize pulley wheels and medium/long cages but unless youre running 1x, a cog over 28t, or have $500 burning a hole in your wallet to get ceramic speed OSPW, no reason to get anything besides standard it'll work just fine. Just make sure it matches your system in terms of number speeds, brand (
sram will not work with shimano shifters and vice versa) and largest cog size. Shifters and cable setup (the latter of which you said you're replacing) have large bearing in shifting performance too so make sure those are in good shape and set up correctly.
The highlighted section in
bold is patently incorrect and probably put out by each brand to try to sell more of their product. Two of my four bikes have SRAM XG 1190 cassettes, Shimano Dura Ace 9100 rear derailleurs, FSA K Force Light and SRAM Red 22 cranks, DA 9000 shifters on one and Microshift bar end shifters on the other. The gear shifting on both is perfect. (I do my own set up work.)
