I'm using many wallets with small amounts in each (Trust, Muun, WoS, MEW, Metamask, Wasabi...) but the one I really trust and have been trusting for many years is Electrum, no doubt. That's where I have a little more accumulated, although nothing that would create a big problem for me if I lost it. For the rest, if you want to HODL, a better option are HWs, but as has already been said, they are not the subject of this conversation.
Trust is the first choice of everyone when it comes to holding altcoins and even if it is closed source, the downloads are in millions, while any person in the crypto field can't name the next best wallets for altcoins, although there have been several extensions and mobile based wallets like MEW, Rabbit, etc. I mostly used MEW, Trust, Rabbit, MetaMask, Solflare, Phantom, and the respective wallets of the respective chains.
And Electrum is the first choice as always for bitcoin, but there is this one hardware wallet, Trezor Safe 5 I think, where we can have thousands of altcoin options.
Anyway, the wallet matters only when we understand what kind of methods it uses to generate the seed phrase and how secure it can be, because after creating the wallet and securing the phrase, we only have to care about the phrase.
