Switching between Minecraft 1.20 and 1.21 really shows how incremental the updates are. Version 1.20 feels slightly lighter and faster on older phones, while 1.21 adds extra polish and new mechanics. Graphically, the difference isn’t huge, but gameplay tweaks are noticeable over time. If performance matters most, 1.20 still holds up well. If you want newer features, 1.21 makes sense, especially when comparing builds like minecraft 1.21.71 apk.
