Sxemini that matrix port wallet is centralized wallet it shouldn't be on the list that you will be recommending a newbie, not your keys not your wallet, I believe the other three are better most especially that electrum one.
As i said, i have searched 10 seconds and my first one was the electrum wallet. Should i invest more time for other people to find something? No not really - i gave only that what i find in this short time.
