Sure there are some differences between MHWorld and Rise in the same sense there are clear differences in design and gameplay between MH3U, MHGU, MHRise. You cannot just compare MHRise with MHWorld and make a (wrong) conclusion Capcom wanted to make hunts simpler and quicker because it's a portable. If what you said were true, then MHGU would have been a different game on Switch when it was released.
One of complaints about MHWorld is that the experience feels kind of sluggish, which I thought was weird because if one played MH3U and MHGU, the controls are even more sluggish and clunky. Maybe Capcom just decided to take feedback from MHWorld and improve upon those in Rise (Wirebugs) to make the experience feel more action-like and fluid.
Personally, I prefer the slower and older style like MHGU but that's just me. I miss the hunting styles (Brave, Guild, Striker, etc) but I can understand why Capcom decided to replace those with the Wirebug system, it seems to be a hit with the MH community in general.
