If you want a lightweight wallet packed with every feature you could need, this is the most reliable, robust and actively developed option there is available. They’ve been around since 2011 and they don’t seem to be going anywhere anytime soon. If you’re looking for something even more secure (but at a price, more than worth it for peace of mind) then you should check out the hardware wallets such as the Trezor and Ledger Nano S.
