Or EM806 (Which seem functionally identical to AM882)

I have AM882's very happy with them.

I think you're better off spending the money on decent digital drivers and a cheap BOB than cheap drivers but expensive controller. It's cheaper to upgrade the BOB than the drivers and gets you working ASAP.
What would be the point of buying 8A drivers to run 3A motors with? "Better" is a relative... is it 4-5 times better than the DQ542MA? It MUST be 4-5 times better to motivate the price difference, but I doubt that. Sure, with unlimited budget, no question about it, but I still doubt there is ANY benefit at all to use 8A drivers to run 3A motors. Also, the UC300ETH is not an "expensive" controller at all, quite the opposite, but again, even "expensive" is very relative.

Also, the OP asked about reliable recommendations, not just eBay guessing. It is pretty easy to list a bunch of expensive parts and claim they are "better" without describing what they are better at and why or how. Of course, very few really KNOWS because very few people actually tried many different drivers, controllers, bobs in all kind of combinations.
