As Ryanair proves, for short haul (up to 3 hours), seat pitch and comfort is by no means as important.
Tricky call actually.
I travel from BRU to SNN. I have a choice, either via CRL direct or from BRU via LHR.
The choice I make is based on flight timing rather than price, and also on convenience; however, the last 2 occassions I travelled BA to LHR / LGW the flights departed late. The first was over an hour late, hence I missed my connection at LHR and the second was 40 minutes late. FR at CRL departed on schedule.
The Ryanair flight was uncomfortable;the seat was fixed and leg room non existent. The BA flight was marginally more comfortable but cost me 4 hours waiting for the next connection! The service was garbage on Ryanair and utterly appaling on BA: "Yes, we are late but you will just have to run through to Flight Connections" - parking on the stand furthest away from FC at T4 helps too!!!
Maybe FR are calling the shots now on service and the majors are responding. Dumbing down. Having said that though I prefer FR to EZY; what on earth is this "Orange" culture bullsh1t?
As for long haul, I've just come back with VS in PE and it's a good priduct and worth the extra money. I flew NW last year on holiday in C class across the Atlantic and F internally and it does make a difference. When I can afford it I will travel in PE or Business long haul.
You pay your money and take your choice!
