Well, I get around the slower loading/firing cycle by not caring about it.

I load in my own time, shoot the birds that please me and have a good time. Actually, I'm pretty quick with the old under-lever - though the non-rebound locks are an added handicap.

I have shot 300 bird days with an under-lever hammer gun. I don't remember them being any less fun than the ones I shot with a Purdey sidelock ejector.
