It really depends on what you want.
If we're talking the bigger Ranger models like RD6 to RD9, then we're talking of seriously heavy and thick knives made out of great steel (5160) for hard use. You can chop and baton with these guys all day long, and if you feel like prying boulders, go for it - you're pretty darn unlikely to break one of these things, and if you somehow succeed, Rangers have a great warranty. I own an RD7, and am very pleased with it. On the other hand, the big Rangers aren't scalpels. These blades aren't for precise work, but that should be obvious just from looking at them. That problem is easily solved though - just stuff a SAK or a small folder in the sheath with the Ranger if you feel like you need a more precise cutter.
As for the Ontario RATs, I have some of those, too. Quite honestly, I don't much like them. These things aren't as tough as the really tough ones, like Busse, Scrapyard, Swamprat, Ranger, etc. And they aren't as good at plain cutting, edge holding and ergonomics as for example Fällkniven, in my experience. The RATs have steel that is either too soft or too D2, choils that don't belong on small to medium size knives, and highly varied fit and finish. Not for me, but there are guys out there that love them, so I think it might be best to try one and see how you like it.
