Not from your list but I would go for this which has been really successful:
most of the php encoder requires server side software installation. Please see the documentation of using them, as each have their own way: e.g: PHP Encoder - how it works
Some more encoders:
For free version, you could try at Monas free php encoder/decoder . They stored their bytecode in variable length format so it can reduce your bytecode size. it seems still in early development, but work very good.
