not got too far in for lack of time, but so far it’s been mostly UI improvements and better graphics, but i have heard that there is some added content as you go further in
have not got to the part where the wii u gamepad used to come into play, but if that has a decent UI i would say it does make the original pretty much obsolete yeah

i guess for context i beat the original once on my actual wii u and once on cemu emulator and am now playing the remaster on ryujinx
