The crushed rock, with the sharper edges is more likely
to lock together to form a sold base for your pavers.
The river rock is better for drainage purpose, since it will take
long for the gaps between the rocks to fill in, thus allowing
water to flow more.
Sand in general is too small/smooth to lock together, but
is very helpful for final levelling and gap filling
for the pavers.
That is generally the rule of thumb I use to determine
what type of rock.
Either will probably work, but you might get a little
more uneven settling with the river rock.
Good thing about pavers on sand is that its fairly easy to
lift a few pavers and re-level (well, ok, maybe that
can add up to a lot of work, but still easier than tearing out
a concrete pour and starting over.

I would then follow up with a sand level and pavers. I need about 8 yard which is about $200 and I've seen river rock/pea gravel on Craigslist for fee. Looking at economics.
