they are pretty close to the same, basic tein coilovers should be cheaper, like around 800 dollars, just basic height adjustment depending on how low you go will determine how rough the ride will be.
should be fine around corners, if you are just going to daily drive the car and want to drop it both are a good choice, i had teins on my integra and im getting megans for my soarer, but teins tend to get rusty, i dont know if thats just me but most ive seen seem to be pretty worn out.
You've been ruining everybody's life and eating all our steak.
