Trust wallet is the wallet that I use to store all the altcoins I have so far, all of them can be stored there with one application, with that convenience it doesn't bother me to save too many phrase.
Dealing with numerous phrases will be too complicated, and having multiple wallets is not recommended from a security standpoint. My opinion is that managing your altcoins should be handled by a single multi-currency wallet. I choose to utilize Trust wallet since Binance owns it and they are a reputable company with a long history of success. If the value of my tokens increases too high, I might switch to Ledger because it is more simpler to move about with a hardware wallet than a software wallet or paper wallet due to security concerns.
