If you have long legs its certainly worth it. Seat recline is over rated and people can get along quite well without it. But, you need to be on the plane early so you can put all carry on bags in the overhead compartment. Best of all, you might be first off the aircraft one day.
I'd say SOME people can get along without it. Flying across Europe on the LCCs that don't have recline is a pain for me. UK to Greece/Cyprus/Turkey is between 3 to 4 hours and I find it quite painful after hour 2. I did an LCC out and BA back once and the ability to recline even just a bit took pressure of by back and made it far more comfortable. I do tend to get up when I can, but the LCC's paid for meal service seems to take longer because of the card transaction times, so I'm trapped in the seat for longer.
