Reliability in general is measured on the basic principle of: does it function within our defined expectations? As long as it's launching, and it eventually responds within SLA/SLO limits, and on failure comes back within SLA/SLO limits, it is reliable. Even with GCP's multiple failures to launch, that may still be considered "reliable" within their SLA. If both AWS and GCP had the same SLA, and one did better than the other at starting up, you could say one is more performant than the other, but you couldn't say it's more reliable if they are both meeting the SLA. It's easy to look at something that never goes down and say "that is more reliable", but it might have been pure chance that it never went down. Always read the fine print, and don't expect anything better than what they guarantee.
