Diamond brand is about the best. Any namebrand chain is good, I use Renthal on dirtbikes and have used RK , DID , EK they all last pretty good if using a standard non oring chain. As long as you do regular maintnence and lubing. O ring chains in my opinion are not worth the money if you lube regularly. Standard chains now days are very durable as long as you dont get the cheap Chinese ebay chains, I tried and installed one and the slack was so uneven I didn't even use it...threw it in the trash and bought a good brand. You need to look close at your sprockets also, if your chain broke I cant beleive the sprockets are in very good shape as far as wear, you really should replace sprockets along with the chain as they do wear in together, normally when the chain is done the sprockets are done too.
