Totally depends on you whether you will be making use of 1 wallet or multiple ones. For me then so far i do make use of 1 wallet on which it is really that on Electrum on which i have saved up my seed phrase on which you would really be only minding about on saving up the keys on which we know that this is really that stressful. The cons on here is that whenever you do lose up that key then you do lose all that 100% of your coins and thats the only problem in comparing into those multiple wallets but the hassle thing with multiple wallets is that keeping the keys will really be that needed to be separated too but of course you will be still needing up that security that those keys will really be that out with other people awareness or attention. Just like others been saying that it will be that up to you on which one you do prefer because everything will really be that still falls down into someones preference and on how good you are on keeping up those keys just like that.
