Jon's 1-Month Rule

Are you trying to figure out if you should buy the expensive version of something or the cheap version?

Just use Jon's 1-Month Rule: Am I going to use this at least once a month?

If so, then buy the more expensive one.

The same applies to time and energy. If you are going to use it less frequently than once a month, then don't waste much time researching reviews, nor much energy stressing about your purchase afterwards, etc.
