Thanks for your comparison which was interesting. As a reader though, on points Easyjet doesn't seem that much better.

Taking your points in order:

Price: Eastjet £150 cheaper Easyjet 1 / BA 0

(But does your £150 compare like for like with a similar ticket flexibility and does it include the cost of seat selection/checking bags/fast boarding and food/drink on board? Also, fares change all the time and there will be times when BA is cheaper)

Check in: Draw

Security: Easyjet 0 / BA 1

Lounge: Easyjet 0 / BA 1

(this has to be a big win for BA, no?)

Boarding: Easyjet 1 / BA 0

(although BA is making big improvements here)

Seat: Easyjet 1 / BA 0

(although I am very confused by this - Easyjet's seat pitch is rubbish at 29" whilst BA's is 30". However BA's seat width is 17" vs Easyjet's at 17.5. So as comfort is subjective I think your point is also subjective here - that you personally find it more comfortable, even if the dry seat dimensions/specs don't support you.)

Service: Draw

BA gives you drinks and a snack (£5ish to purchase?). Easyjet provides a higher standard of food to purchase. Personally, I'd call this a BA win, but I respect your point.

Arrival: Draw

Easyjet flies from Luton in this case. This may be more convenient for you, but for many people it is a deal-breaker. LHR can bring great advantages in time and connectivity. You also don't mention Easyjet are a point to point airline so no good for connections either.

So on a points system only from your post, I make it:

Easyjet 3 / BA 2 and that's not factoring in LHR and my other points.
