The ES6 bookmarklet can be easily shrunk by 13 characters, taking it to 121:
javascript:for(let e of document.querySelectorAll('link,style,[style]'))e.style.cssText?e.style.cssText='':e.outerHTML=''
javascript:for(let e of document.querySelectorAll('link,style,[style]'))e.style.cssText?e.style.cssText='':e.outerHTML=''
It will work in Firefox once they enable `let` without specifying the script version.
It will work in Chrome once they fix for-of and once they make `let` work outside of strict mode.
