I can't recommend any specific brand. (Sorry!) However I might be able to give you a useful pointer:
When I was working at a railway station I helped thousands of passengers with their luggage, including getting it up and down lots of stairs. (They've got it easy at that station these days though - they've installed lifts!).
Most customers used suitcases with wheels, which were meant to make them easy to handle. However I quickly learnt that suitcases which have wheels close together are very tricky to handle, as they constantly try to tip from one side to another, almost ripping your wrist off as they do so. (It's often simpler to forget about using the wheels altogether and to simply lift the suitcase clear of the ground).
Those suitcases which had wheels set well apart though were a joy to use and, even when heavily loaded, required very little effort to manoeuvre.
So I strongly recommend avoiding anything like this (with wheels close together)

and to look for something with a low centre of gravity, with the wheels set wide apart, such as these from Samsonite:
