I used to use Opera for many years, and IMHO it was almost always the best browser around feature and speed-wise. The only thing holding it back was the rendering engine.<p>I ended up making the switch to Chrome when Opera 12 came out and was too buggy for my taste (it was the last straw).
It took a while to make Chrome feel Opera-ish, but I still miss Opera from time to time, you know, because of the little things.<p>One thing I wish Chrome had is the ability to select hyperlinks. Opera would let you click and hold the mouse cursor anywhere on a hyperlinked text and select it. If you try the same in Chrome, it will try to drag & drop the link instead of starting a selection. In fact, sometimes it gets really tricky to try to select hyperlinked text.
