I don't think I have seen any pattern. If things are broken they are broken, bugs don't look at the release classification. (I don't know whether Ubuntu project has stricter release quality criteria for LTS, but I think the biggest limiting factor is testing and bug-fixing resources. And they don't magically grow when its LTS time every second year.)
Maybe the chance of getting a fix in the same release is slightly better if it is LTS. For non-LTS you wait half a year and there is the next release. Just a feeling, though. I have no statistics and generally the number of serious breakages is too small and/or affects only some particular hardware, so statistics might not be very useful.
