Internet Explorer 11, New Good or Still Bad?

Ever since IE11 Release Preview has been released yesterday for Windows 7, the questions everybody have in mind are?

1. Will it be faster? My answer is yes, I notice the benchmarks, it's doing well, far better than both Chrome and Firefox. I have taken this by surprise!
2. Will it be safer? I can't answer this one as I no longer a fan of IE due to its reputation for its infamous vulnerability and it's a lovable favorite target to hackers, malware and the such. Since I've been told in the past that we should stick to the competitors like Firefox & Chrome, so I can't tell how IE11 stack up on its security today. Even though IF they claim IE11 is now just as safe as the competition, but I still have my doubts when the hackers continue to attack them & finding loopholes a lot more often than the competitors.

With Windows 8.1 close to release by less than a month left to go (Even some box sets announced & the free upgrade to those with existing Win8), I'm really happy and can't wait to test it out but will only install it once Windows 7 gave up and needs a reformat. As for IE11, will wait for the final version and the reviews from many computer websites, not just that, I'm sure Mozilla & Google will continue to step up the game in order to keep our loyalty strong with their browsers rather than IE11. What are your opinions? Particularly IE11's security. Will you use it when it's released?
