If PAPIs are there, it's great to use them and be familiar with them, as anything that makes things easier is good.
However, it is true that you don't want to be so reliant on them that you can't judge landings on a runway without them. When I was learning my instructor sometimes got ATC to switch the PAPIs off so I could approach without them - why not see if you can do that?
If you always have the PAPIs, your first landing on a runway without them can be nerve-racking!
