To be honest, I'd go with the Express 4k+. The stick comes with a "long range wireless receiver" that on the surface sounds like a good idea, but if you look through this forum you'll see all the people that have a broken one and no way to replace it since it's out of stock and the stick is useless without one. The remote that comes with the Express 4k+ is also Wi-Fi direct, so can only be paired with one device at a time. The Express also has the advantage that you can use any universal remote that supports Roku devices to control it. With the stick, you're stuck with Roku's remote.
