Lots of things can be the same, but there are a lot of differences too. I don't like to make general statements because there are always exceptions, but most of Minnesota's lakes are natural lakes. No dams or river channels which also means not a lot of standing timber. Minnesota lakes are frozen for half the year and they never warm up as much as southern lakes do. Lots of clear water up north also. The vegetation is often different and the clear water means it will grow deeper as well. Different species of bait fish and predators. Minnesota has walleyes, pike and Muskie.
Bass are targeted a lot less up north because the walleye is often the king up there, lots less pressure on the bass. The lakes up north are generally less fertile and with the shorter growing season, the bass have less to eat and seem to feed more often making them in my eyes, easier to catch. They also don't get nearly as big. With considerably less very heavy cover and smaller fish, lighter tackle is generally used by those that do bass fish. A lot more anglers use spinning gear than you might see down south.
Bass are bass and what works down south will work up north but conditions can be so different that the best options may not always be the same north to south. For example, on a northern lake I fish, there often is a mat of vegetation a couple of feet thick on the bottom. The standard jig and pig or weighted Texas rigged worm can't be dragged along the bottom, it would just disappear in the gunk. I know there are similar lakes down south, just as there are hard bottom lakes up north. So when the conditions call for it, be prepared for a few different circumstances where other options might work better.
