I've seen many people saying he/she prefers Aristocratic Elite in late game because of stability bonus. I'd like to share what I've found in 2.2. I conclude Aristocratic Elite civic is weaker than alternatives.
Here is a picture from my last finished game(late game) :
Note that I built this planet planning to switch to Byzantine Bureaucracy but game ends before I switch.
Example of typical basic planets.
1. Stability bonus is nice but it is additive. It is better to get more base production than to add % bonus.
For example, in the above picture, my 60 metallurgists produces 349 alloys. This means they are at 193.8% efficiency. 112 researchers produce 1379 physics, which is at 307.8% efficiency. That's why I didn't bother with 6% stability or 3.6% bonus I can get. It doesn't improve 3.6% from current state, marginal bonus is around 1.8% (in alloy) or 1.2% (in research).
2. Stability can be improved by happiness, which is easy to pick in late game.
In the example picture above, 247 pops are at 91-98 happines. This is from (default) decent livind standard, festival of worlds(Artisan troupe bonus), life tree bonus, faction approval, food policy and high amenities. High happiness leads to high approval rating then higher stability. Combined with harmony bonus, deep space black site, stability is around 84 excluding capital and police state bonus.
Note that typical basic planets have 97% approval rating, thanks to 20% high amenities bonus.
3. Comparison with alternatives (Technocracy, Byzantine Bureaucracy, etc)
Aristocratic elite provides 10% stability which is flat additive 6% production bonus. In terms of alloy, this is 3% marginal bonus due to already high efficiency. If I wanted more alloy, Byzantine Bureacracy allows me build avg 2 more foundry districts(up to planet size) in ecumenoplois without overcrowding. 20 more metallurigists outproduce 10% stability. If I wanted more science or unity, Technocracy or Exalted priesthood provides base research or unity, which outproduces 10% stability. I excludes building noble becuase 5% stability can't compete one building's base production.
