This is difficult to answer clearly. It depends on a multitude of factors that can not be exactly calculated. First off, you need to specify whether you want to gather affinity for your warframe / syndicate reputation or for a weapon. In both cases, you'd want to go to missions where a lot of enemies spawn at a level that you can just kill them still quickly. As you can see from the affinity density graph, taking more time to kill higher level enemies is not worth it, just go for the highest that you can kill fast.

Now, if you want to level a warframe or syndicate rep, you should have a warframe in the squad that can kill enemies over a large area very quickly with his abilities, like a Miasma Saryn, Bladestorm Ash, Javellin Excal, Mag, stuff like that. If you want to level a weapon, you should unequip all other weapons and take a warframe that can buff his own weapon damage (directly or indirectly through debuffing enemies) like Roar Rhino, HoM/Eclipse Mirage, Nova (the Mol Prime chain reaction kills will count towards weapon kills). Alternatively, you can take a strong second weapon with you as well and use this to kill enemies, there will also be some affinity shared with the other weapon, and you can thereby farm something else simultaneously since you don't have to play lower level missions.

High spawn rates often occur in higher level Interception, in Excavation, Survival, Mobile Defense.

An aspect that does make higher level missions more rewarding in terms of affinity which I haven't discussed in the article is the higher frequency of Eximus enemies there. These often give more than ten times as much affinity as normal enemies, so any place with lots of Eximus is great for farming affinity.

Just don't forget that kills through warframe abilities will not grant any affinity to your weapons, while weapon kills share half the affinity with the warframe.

If you start leveling a warframe and weapon from unranked at the same time, you must do exactly twice as many weapon kills as ability kills for both to reach max rank at the same time, if you bother about that (usually, it works better to not do that, instead starting a new weapon with an already strong frame, then start a new frame with an already strong weapon).
