I'm going to let you in on a bit of a secret. Don't use stunts. No, seriously, don't
If you must, pick somewhere between 1-3 stunts that you absolutely know without a doubt will get used every session, and you know they'll have a good chance of being useful several times a session as well.
Reason: Stunts are a permanent Fate point expenditure, that give the same benefits that spending a Fate point would when they are used. If your ration of stunt use is lower than once per session, you've spent permanent Fate for something that isn't as helpful as an aspect invocation. If your ratio is just at once per session, you've spent permanent Fate for something that will be as potent as an invocation, but does not have the variability that you'd get from the ability to choose a bonus from among 7 different aspects. If the ratio is higher than once per session, then maybe, just maybe, the math comes out in favor of the stunt.
Stunts that give +1 bonuses instead of +2 are even worse, and need an even higher ration to be worthwhile.
The key to picking good stunts is to choose those that are absolutely core to what the character does, so that you have a really good chance of maintaining that ratio of stunt use per session.
