There are lots of pluses and minuses to the iPad browsers.
My favorite browser is Dolphin, though I'm not using it right now because the latest update has a bug which causes it to crash on one of my more visited sites (The Verge). However, I love the ease of which you access bookmarks, the minimal browsing bar, the unified URL and search bar, the quickness of changing settings, etc. It's the most intuitive to use and the fastest to access quick sites.
Right now I'm using Safari until Dolphin updates and fixes that little bug, because it's got quick access to bookmarks via the bookmark bar, plus good tab management (though I hate Safari's multi-page look on the phone, so it's my least favorite phone browser, but it's good on the iPad.) Down sides to Safari are the fact that it often reloads tabs spontaneously, which will often wipe out things I've typed in one tab, and the fact it doesn't have a unified search bar.
Chrome is good, minimal, fast and has good tabs and a unified search bar. However, I just can't use it as my daily driver because I HATE how bookmarks are managed. It is a minimum of two taps to access my bookmarks, plus a third tap to go to it. I quickly get frustrated since I'm used to just swiping from the left to access all my bookmarks in Dolphin.
