[2022] What are your "I don't care how many Forma it takes" items in the game?

I love the Akbronco Prime sidearm, but it's not very good past middle game... unless you dump 7 Forma into it, then it's pretty great.

What are the weapons and frames that you love and will make viable no matter how many Forma or potatoes it takes?

Edit: this ended up being a great discussion and I read so many comments that made me smile.

Thanks for being a cool community!

Edit 2, in case anyone is as curious as I am:

The most popular answers seem to be;

Frames: Sevagoth, Valkyr, Rhino Prime and Baruuk

Weapons: the mk1 weapons (especially the Braton), the Acceltra, and the Grakata

Generally: Primes, anything you've got a good riven for, and items that fit a theme for a warframe you love.
