I think majority of us are using MEW but be careful on phishing or else all your hardwork be gone.
well, it's simple to use and safe as well if you can protect your private key xD
MEW is designed for hardward wallets though, it's only safe to use without one if you're not using your key/seed to login. Ie you don't login.
Don't mean to sound rude, but otherwise it's really not safe logging in like this (says it on the website I think).
Hence MetaMask 
You're right I login in through MEW address only for viewing my tokens.
If you just want to see your tokens, why not just use EtherScan? Unelss you need to make transactions/trade, there's no reason to login.
Took me a while to realise this tbh, but it's worth knowing...
