Safari is best because that is what Apple tells you and forces you to use.
Chrome is better for me. I came to that decision, and not Apple. I use it on my mac and lo-and-behold it is the default browser. What a concept.
It's rather sad when the only defense iOS defenders have for its shortcomings nowadays is "why?"
Want more than 8 tabs? Why?
Want a better default email app? Why?
Want a bigger screen? Why?
Etc., etc.
So you go right ahead and keep asking why as the competition screams: WHY NOT???

Actually, Apple has conditioned them not expect much of anything. Look at iOS. Looks the same as it did in 2007. iFans response to this is "Why fix it?" To that I say, well why bother updating the OS at all then?
But of course, as soon as Apple steals a Google idea (pretty much all they have done in iOS5 and 6, still get a kick out of Apple calling "Priority Inbox", the "VIP" Inbox or their inability to copy Google Maps) - then it becomes all praise for these ideas by the fanboys. Here are some classics, from this very board:
2011
"iPhone is perfect at 3.5 inches. I don't want a bigger phone. I'm glad Apple kept the 4S this size"
And now:
"iPhone 5 is the perfect size at 3.99 inches. I don't need a bigger phone."
2011
"3G is fast enough. I don't want LTE, cause it will effect battery life. LTE is not needed anyway"
And now:
LTE on the iPhone 5 is amazing! This is awesome. How could those Fandroid fools buy the Nexus 4? It doesn't even have LTE!"
2010:
"iOS4 is perfect. Why would I bother with a notification center, when I can just open the email or sms app?"
2011:
"iOS5 is awesome! Check out the Notification Center. It even tells me the time! So innovative of Apple!"
2013:
iFans still insist things like a 'back' button, LED notifications, external memory cards, 2gb of RAM, ability to place icons where you like, use widgets, and so on is superfluous and not needed. But as soon as Apple adds it, well, it becomes the greatest thing since sliced bread. NFC is next and all the iFanboys will come out in droves, claiming how innovative Apple has been in bringing the technology to the iPhone 6.

Why? For some gimmicky feature? Because the best browser for iOS is Safari no competition. Using Opera or Chrome on iOS is just being a hipster.
Yeah, why give users options! No one should be allowed to use anything other than Safari, cause it is the awesomest browser ever made. It can do everything.
You know why Safari is smooth on iOS devices? Because Apple refuses to allow other browsers access to their API. They are doing everything in their power to force you to use their stuff. It's a good browser, not saying it isn't, but is it really the best for every single person? Answer = No
I use and prefer Chrome. Luckily, I have a phone that allows me the option to make it my default browser. Or I could make Firefox, Opera, Boat, Maxthon or a whole slew of other browsers my default browser. Why? It's called choice. Maybe you live in North Korea and are used to a Stalinistic dictatorship, where having choices are viewed negatively? I don't know?
