This depends on each person, I personally prefer to keep it in the form of paper that I write on myself and I also print it on an iron plate and then keep it in my wallet. The point is, I don't want to save it in soft file form because there is the potential for hacking or leaking.
That's true storing seed phrases on soft file there is always a potential risk for hacking or leaking. So now if we consider these aspects, the seed phrase in the soft file is very risky. But in many cases we use the soft file despite the risk because it can be used anytime from anywhere in the world. However, keeping the seed phrases backup in the hard copy and maintaining it properly will be the best option. My suggestion would be to have multiple recovery sources for seed phrases for recovery.
