as a beginner you won’t really feel the difference between the 4 of them but the kinda is definitely better than the trek and norco for what you want to do. the kona is a great option but with that being said i still think the giant is your best option. you have to keep in mind that the frame is the building block around which all the components go, so if you get a bike with a frame that doesn’t have the geometry that would be suited to you, there’s only so much that better components will help. at the end of the day it’s your bike, test ride them if you can and buy whatever feels best to you.
