I did not wait any longer to download Opera 9.5. It’s still fresh, and because I’m comfortable with this browser. Because I do not have many addons — like in Firefox, I just upgraded it. The upgrade process was easy, just like doing a fresh install.
The new interface looks great and well-polished. The window tab is redesigned and I think it’s much better than before. Look at the screenshot below. It uses the standard skin, special effects-enabled with “Sand” color scheme.

I am not saying that I do not like the new skin desin, but I like to have it simpler. Previously, I use another skin called “Flat”. I want to keep my Opera clean so that I can focus on the website content. Here is my current skin using the same color scheme. It has slimmer tabs, not many colors, and smaller icons… and I like it.

I do not use all features offered by Opera because I do not use Opera as my other applications like RSS reader, email client, or chat. I choose to use web-based service like Gmail and Google Reader. About other accessories, I have some Opera widgets installed: Ruler, The Colours of The Rainbow and CSS Help. Well, I miss Firefox when it’s about extensions/addons. But, it’s fine for me if I do not have them in Opera. :)
I still want to have Opera as my best browser, but I still find it hard to have it really customized for me. I’d like have Greasemonkey really works in Opera. I know, it’s said that Greasemonkey already supported by Opera since Opera 8.0 (more about User Javascript). But, I still find it difficult to have work. Anyone? Overall, I love this release and I just hope there are more official tutorials to get the most from Opera (for users who already love Firefox); something like: How to get these in Opera?
