Editor's choice php/python/js for ipad?

Carefully googling, I found two options: Markup and Gusto. Actually both cost money and so a question to those who yuzal: which is better? For both applications buy as you do not want. Well, or maybe there are some other options?

PS the Reviews I read, mixed feelings remain
