Dificult Amiga x PC ( and emulators)

HI all

Im not played on amiga , i mean the in the original hardware . I have experience on Snes. I have a snes many years ago, and played tournaments actually, games like Top Gear, Rock n Roll racing... etc. i will use Top gear to an example. The game have a very diferent experiences on Snes x emulators. The USA and Europe versions already have huge diferences in the console, fuel , nitro time, and your strategy change when play on diferent emulators. The tracks that u need 1 stop in Europe version u need 2 in USA version. Emulators like Zsnes execute the game with 60 fps in USA version. If u play in retroarch well, its another game!!. The point is: For SWOS, WINUAE and FS UAE have diferences on gameplay ? i dont can see diferences... But well, im noob. And for original amiga? the same gameplay? the CPU are the same dificult or change a little bit?

i played the mega drive version of Sensible soccer. just score 12 goals. The cpu do nothing.PLayers dont lose the ball etc
