IMHO BA is a much better airline, LCCs are indeed for the traveller who is tight to be really honest, but still some have to use LCCs as Legacy’s do not serve the route required, but say I wanted to go London to Barcelona i’d use BA anyday over the LCC for the TWP (tight-wad person – in such a case).
After reading the Airliner World Article “Is low cost truly low cost” i have turned against LCCs completely

What the lowcost airlines have done not just for themselves, but their employees and the airports they fly to is fantastic. Let alone the travelling public. I’ve been on four holidays in the past year, 3 of those were because I got cheap flights with easyJet and Ryanair. The money I saved on flights (by flying direct aswell btw, remember from alot of regional airports you have to fly via somewhere with the likes of BA) got me an extra night or two away and in a better hotel with more drinking money.
