As a personal note, I do not think the thing setting apart any of those products (Xcache included, ioncube afaik is dead and buried) is its sheer speed or memory usage. What really matters is stability under heavy load (including opcode-cache purges under access storms). So be prepared to stress test before going live, and to install your 2nd choice if the first one turns out to crash in your setup - I personally have seen all of them crash and burn in at least one particular php installation, so I have no real personal favorite. You can also take into account that APC is maintained by php-language developers, while xcache and eaccelerator are currently a one-person project. It might be important if you like support contracts and long-term platform sustainability. Just google around to see how long it took for those 3 products to support php 5.3 to get an idea...
