Opera is indeedy-doody fast.
If you've borked Firefox on your laptop, find the profile and NUKE IT FROM ORBIT WITH A SPADE!
If you go to Tools>Appearance or Shift-F12 you get to the Skins menu. Click on the 'Find More Skins' radio button and wait a few seconds. A 'Opera 9 Classic Skin' option will appear. Install that and Opera looks much better.
I use Opera because I prefer the amount of customisation and fiddling you can do with it. If you search for speeddial.ini on OcUK or Google you'll find out how to increase the number of websites you can have showing on the Speed Dial. It is set to 9 by default but you can up that if you have more sites you regularly visit.
If I were you, I'd type 'Opera:config' into the address bar and click on the BitTorrent link and UNCHECK the Enable box for BitTorrent. Opera's torrent feature is quite poor compared to the rest of Opera and you might as well carry on using uTorrent or whatever you use.
Opera is more customisable and quicker than Firefox I would say although Firefox has a better extension system. You can't really get that with Opera although there are widgets to install but these are more like mini apps to help you with stuff not really browsing related.
If you pop into the HGP forum you'll find a thread with a custom black skin for OcUK. You can download the code and save it into a .css file if it isn't already then go to OcUK, right-click on the page, 'Edit site preferences' and go to Display tab. Then where is says 'My style sheet', navigate to where that .css file is, select, press OK and refresh the page and you should see OcUK in a new light/colour.
What tchan_4 says is quite true but it isn't as if the sites just don't work, they just don't look 100% right all the time. There are a few graphical glitches that are obvious on the pages. You can try and fix this by identifying or masking Opera as Firefox or IE to try and trick the website into rendering better.
I wouldn't say the websites have priority for IE, FF, Chrome and Safari. Its just the way that Opera interprets HTML, quite strict really, so other sites which aren't coded as well as they could look OK in IE because of its low standards, but look poor in Opera.
Any other problems or questions, don't hesitate to ask or search OcUK for previous threads. A certain Leperous Dust person will be along surely to convert you to Opera, MediaMonkey and Digsby all in one go!
