You'll find EXACTLY the same questions (and answers) in almost all the online databases (and also in your exams).
What you really want to know is how many of the questions in your upcoming exams you will NOT have seen before
Every online database has a different interface, allowing you to work through the contents in various ways - this allows you to choose which one works best for your style of learning.
Every provider manages their own update process because the aviation authorities don't hand out their current questions...
So at the end of the day you make a choice, which is often based on what your peers recommend - after all they've probably already sat some exams and so have a good idea if what you see in the database is an accurate reflection of the real thing!
After all the CAA exam fee is £69 for every exam - so you don't want to be paying for a resit do you?
