lalo isn't as porous, "that's true", but it is covered with great colorful coraline algae. I got the lalo and I can confirm that.
I would just recommend to get it cured if you can and if you can't..."make sure you cure it", especially if it's going into an already established tank. I just threw it in my tank with grave consequences so please don't learn the hard way like I did.
Also, the more diversity the better, so if you like both rocks then get a little of both and don't be afraid to mix and match...."good luck"
