At the end of the day... there is no reason why you can't use both Electrum
and Ledger Live. I do... and it doesn't cause any issues.
Ledger Live is necessary for installing/removing coin apps, doing firmware upgrades etc. So, you're definitely going to need to use it at some point, so you may as well install it and experiment with it. It's quite handy for viewing your entire portfolio as well if you are holding multiple coins).
But I also appreciate some of the more advanced features in Electrum, so will use that as well when I need to make sure of those features (coin control, pay2many etc).
In Ledger Live App
I have read that there are too many major issues if you are operating Windows OS (I am using Windows 10)
Nope. Ledger Live works perfectly fine with Windows 10. That is exactly what I am using. The issues people were having was trying to use Ledger Live on unsupported versions of Windows... ie. Windows 7.
There were some recent issues with some overzealous antivirus programs incorrectly detecting the installer as being infected ("false positives")... and some recent issues with the update process being a bit screwy... but as far as I'm aware, Ledger Live+Windows 10 is OK.
