How do you manage the Warframes you use?

In my case, I'm sure I have a Warframe ready to make a specific type of mission or contract easier.

Khora for farming for a while when I'm short on a certain material, Hildryn when I know I'm going to get destroyed on the mission and I want to at least ensure good survivability and some damage, Mesa for contracts on Deimoss/Cetus or extermination missions where I want to kill everything in style, also for hunting my liches, and finally I have Uriel for defense missions or where I need to move from one point to another several times and take out many targets at the same time. Uriel is my second safe pick when I know I'll survive well but I need a lot of damage in a very large area.

Soon, I'm going to add Voruna for capture, rescue, and survival missions while having fun. I don't know what other types of missions she might be good at.

What do you guys do with all the frames you build? Do you use them a little and then abandon them? Do you have different frames for every situation like I do? Do you use them depending on your mood? Do you have a main character?
