These threads always amuse me... "Is product 'X' that costs a third of product 'Y' just as good?"
We all know the addage that "You get what you pay for" - so no, Leofoto is not "just as good" as Really Right Stuff. The question should be, "Is Leofoto good enough for my needs?" - and the answer I'd bet for 95% of the folks here is yeah, probably.
RRS is, and always has been, one of the top brands in the photography field, and since expanding into the shooting sports industry they are at the top of that game as well. That being said, are you:
a.) A professional photographer that earns a living at it?
b.) A professional hunting guide that earns a living at it?
c.) A MIL/LEO sniper... who earns a living at it, or...
d.) Have a couple grand sitting in your checking account that you don't need for better optics, or ammunition to practice with, or to take a shooting course with, or to actually spend on tags to go hunt with; and are happy to part with, so you can have bragging rights at the next NRL/PRS match?
If any of the above are true in your case, then yes - you should buy an RRS and you will be entirely happy with your purchase. If you're not one of the above, then is spending three-times the cost of a Leofoto (admittedly a knock-off, but that's another discussion) for maybe 20% better performance, a wise decision?
I'd say that unless you have a lights-out shooting rifle, alpha-level optics on it and around your neck, and already have trophies on the wall (taxidermy or plaques, or both) then you should probably think twice about where your cash is going.
