I don't know the difference since I've never used the 2424, but I can tell you about the r4512. I've had mine about 6 months now and it is outstanding. I looked at a number of table saws, Grizzly, Shop Fox, Jet, etc. For the price you can't beat this saw. However, the lifetime warranty will only come with a purchase of the r4512, which would be a deciding factor for me.
