I see that some uses streamline, someother use kuertee auto-save and time and so on, do I really need to use an alternative way to save my game?

Those just make timed autosaves, making it less likely you will lose progress if you die or crash. If you don't require this, don't use autosaves or quicksaves and you'll be fine.

No you can deal fine with the normal saves. Those are just for convenience.
