TEQ Jaco has the same passive as that INT Chiaotzu, and AGL Devilman has an ultra-rare chance to one-shot the enemy. Other than that, I only save SRs that Dokkan into SSRs, and SRs that share the same name as SSRs of which I want to raise the SA - any SSJ Goten or SSJ Trunks, for example (so I don't really save them, I use them for their 50% chance to raise the SA). TEQ SSJ Goten and INT SSJ Trunks Dokkan Awaken into SSR SSJ Gotenks, so they actually have a 100% chance to raise the SA of any SSJ Gotenks.

On the character list you have the option to display only characters with an available Dokkan Awakening, or only characters with unavailable Dokkan Awakening.

Another thing to keep in mind is that only a few Supreme Kai's Trials require Fierce Battle, but there are many other missions with other requirements (Link Skills like Z Fighters, Turtle School, Brutal Beatdown, Prodigies, etc...), so you might want to check what those requirements are before selling units with certain Link Skills.
