windows desktop eth wallets

ETH seems a little odd to me vs. other crypto currencies in that there is no official wallet for it. Consequently, I've been trying to figure out how to generate a wallet and use it with a ms windows desktop wallet software. This has been pretty confusing.

The only way I've found to generate an eth wallet is with metamask in the browser. I took that seed phrase and imported into coinomi but the address in coinomi when I click receive doesn't match the public address in metamask. This seems unexpected to me.

What am I doing wrong here? Getting a little frustrated with a process that seems like it should be pretty straight forward.

TIA
