Since there are some problems that have been reported regarding this wallet, it is better to use several wallets such as:
-
Trustwallet: Open source, running on Android and iPhone, offers many possible altcoins.
-
HODLER Wallet: An excellent alternative, supports many languages, full control over coins, ERC20 scanner.
I think if you use a variety of wallets, you may reduce the risk of keeping all currencies in one wallet.
I agree with tryninja in this one. Coinomi is a good wallet. I use it for years and never heard of anyone having problems.
The only problem I know someone had is with the desktop version, when it was recently released, and it was a very suspicious situation (the guy hold his life savings in a new released wallet, which is strange to begin with)
I never heard of those two wallets you mentioned. They are not as tested as coinomi, which is one of the oldest wallets out there
However, the best multicurrency wallet imo is ledger nano . It support almost all 1500 shitcoins that coinomi does support, and with 99% security
