I'm not much on the brand name pushing that goes with a lot of hobbies and tools, but I have 8 or 10 bowl gouges, all of them various powder metal alloy configurations; 2030, 2060, Pro-PM, and A11/10V CPM. There is only one tool manufacturer that makes an extended reach bowl gouge; Doug Thompson makes a tool, the "Bill Grumbine" signature gouge, which lets you turn quite a ways off the toolrest to get into deep pieces, AND lets you use all of the flute to the very end without being unbalanced. After using one gouge all the way to the end of the flute I bought a few more.
As far as scrapers go, Thompson introduced a "monster scraper" that is 12" long. I would have purchased this if I hadn't bought a tool marketed through Woodcraft, their "superlong bowl scraper" which is 16" long without the handle. Its a good tool, but I like to sharpen as little as possible; a few extra $ is worth the time savings to me.
