Without wanting to appear tribal, I wouldn't treat the number of aircraft FR has on order necessarily as an advantage. Given the overcapacity in the European market (and I don't think we have seen the peak of that yet) having an endless stream of new aircraft could well be a big headache for Ryanair.
The proof will always be in the financial performance of the carriers. Easyjet are currently doing particularly well and have had a stellar performance in recent years. Ryanair may well be adopting the highly successful Easyjet strategy but they are doing so 3 years later and simultaneously have to improve their image. That won't be easy. (No pun intended)
