I really have nothing to compare to, but the Lalo rock I have is very porous. More caves and holes than you can count. I ordered twice, each time was 30 lbs. The first shipment came with a basketball sized piece and some smaller pieces. The second shipment came with some very large, flat, strange shaped pieces as well.
Lots of color and Coraline algae. It has been in my tank for a few months now and I really can not say I have had much problem with pests at this point. It seems to me that anytime you harvest from the wild you are likely to bring home some surprises.
For reference here is s photo of the rock in my tank. There are other photos in there of the rock as it was unpacked too if you care to browse for them.
