It's only old to you, he asked because he was unaware...although for downloads sake he might have tried 1964 anyway himself instead of asking an opinion on a forum, but so long as he isn't spamming or trolling it doesn't matter, right ?
You are correct though, when I was using 1964 I found straight away that it was leaps and bounds better than PJ64 because it had one crucial thing that PJ64 STILL doesn't have yet, that being the ability to set certain roms to use certain plugins. But, there is a big flipside, I found 1964 to be unstable, many a time I would be half way through a Conkers Bad Fur Day session and 1964 would simply freeze crash. I have next to never had that problem with PJ64. So for now I just use PJ64 too and put up with the constant plugin switching, but I wait for any updates that include rom specific plugin options as and when they are done.
