You can't measure the release by Nexus standards. The Nexus-release is a glorified beta-test.
OEMs can access Google's internal Android's sources before they're open-sourced. Nexus isn't a benchmark - it's a public release of already finished firmware, and patching up the final issues, OEM's updates should follow within one-two months, not 6+ months or more. Since Note 3 is still one of their top phablets with no successors, they had to update it quickly enough to make people stay on their devices - if you'd spend 650 pounds on a device and then wait 6 months (if you're lucky) to get an update, you'd probably be pissed off (and rightfully so). They abandon their low-end devices or older flagships quite quickly.
For example, Galaxy S2 (which I own) was updated to 4.1, but not any further, despite being perfectly capable of doing so. According to Samsung, it's because they ran out of memory with TouchWiz
bloatware 99.9% folks never use
features, despite the fact that S3 was updated to 4.3, and had 1GB RAM - just as S2 did, S2 /system was 512MB, /preload was another 512MB. S3's firmware was ~800MB. So, really, it's just them having crappy business practices.
Another example? Galaxy Mini 2. It's moderately popular in Poland - it's cheap and "just works", and was released with 2.3 - had a couple of point releases, but never got past Gingerbread. There are 4.x ROMs for this phone here, and they're fast and fine. Capable - just Samsung's not interested. Okay, they were - and eventually announced that no update will be released
I'm honestly admiring Microsoft for their WP8.1 upgrade policy.
