I'd love to hear about the errors you're experiencing; if there's any bumps in the road we want to smooth them out ASAP. Please email cloud-sql@google.com with your instance names and the error message, and I'll get someone to look into it for you. Second Gen is indeed always on. Crunch the numbers for your use case, I've been told by the pricing mavens that for many use cases Second Gen ends up cheaper. And yeah, Second Gen doesn't follow your AppEngine app the way it used to. This will be a call you need to make based on your use case. If you are low-traffic and highly latency-bound and your app runs on App Engine, first gen may (may) be quicker. For other bounds (I/O, RAM, CPU) you should expect better performance from Second Gen.
