That sounds like a personal preference and experience and might be down to your technique. The general rule for serve receive is though: "if you need to push and can't open up, then push very spinny with good placement so that the only way the opponent can open up is slow and spinny". If heavy backspin balls where generally easier to loop kill, nobody would receive with heavy backspin
I think it's down to recognising heavy and light backspin balls and choosing the most effective way of dealing with them.
I have found that there is an evolution after first learning to loop backspin that teaches different ways of looping each type of spin.
For example I know a player (a better player than me) who, against heavy or light backspin balls, can slow loop with extreme rotation OR power through it with more speed, against almost anything.
He chooses different approaches for different players depending on what the can deal with because some people can deal with spin and some are better at blocking faster loops.
I speak quite a bit with him and occasionally we train together and his usual approach is, the heavier the backspin the more comfortable he is to snack through it.
Anyway my main point is that there are options available depending on ability but the consensus we've arrived at (me, him & coach) is that powering through more gives more consistent results V the heavy backspin.
Only felt the inclination to mention it as it was the opposite of what you'd said above.
Not being condescending here at all, I know my level doesn't place me where I can advise most peo but it may be something to experiment with on your end? Or not 🤷
