which framework is best
well which one are you experienced in
which one gives the best job propsects
which one helps you deliver stable code that works
which one is going to be around over the lifetime of the project.
one of the bugbearrs of PHP and and much of the opensource movememnnt is that you don't knwo with user contributed packages is will it still be around in n years. will it still be supported
does it acutally work fully as you'd expect. often you get what you pay for. if you are not prepared to pay for it then dont' be surprised if it dissapears or doesnt' do the job.
