Why should I NOT Jailbreak?

I have read and seen tons of posts about why I should jailbreak, however I am interested in knowing why I shouldnt. I know for a start that you lose security, some apps dont work anymore (especially banking ones), lack of stability, etc. But I would like to know what you guys think!

Some background information about me:

1. I switched from Android to iOS mainly to stop myself meddling with the phone, leaving my phone in a state where it is unusable for a day or something (flash a ROM you dont like, for example)

2. I want a reliable daily driver

3. There is temptation of personalisation

4. I do have an iPad Air, is it a good idea to jailbreak that and keep my iphone as the daily driver?
