Oracle's administration interface is horrible. It's an obtuse nonsensical hierarchy, probably specified by someone non-technical writing a requirements document in a vacuum. It'll take you an afternoon to figure out how to get your instances set up, upload your initial image etc. Also your instances will always be behind NAT (having internal IPs), which is odd.
Its redeeming feature is having a free tier that isn't Google. The problem with using Google's cloud is that if someone hacks your account and runs up infinite charges as a personal user, you can't file a credit card dispute without disrupting your entire relationship with Google.
The cloud market still has healthy competition - eg Linode, DigitalOcean, Vultr, and innumerable smaller companies. Patronize them, rather heading than to a different behemoth.
