Leaving a good wallet just because it is not doing for what it is not made, is kind a not a good thing, I am not a regular user of Electrum but still, if you want to look at BTC's updated price then go for some exchange where you want to sell it, don't even see on CMC, or coingecko, or on trading view, because they don't show the exact price, instead, they show average price. If you want to be so precise in terms of BTC price then only check the rates on exchanges or places where you want to sell.
And talking about Mycelium's recommended notification, that is frustrating. You can block such notifications in the settings, once you go in the app setting, there you will see notifications and when you will expand that bar, you will see many types of notification option and one of them will be recommended notification, just block them this way you won't be missing any important like TX notifications. But to remain safe, I suggest to not do that. Still Electrum is in my favourite list even if I don't use it regularly.
