Wet vs Solid meth

Hi all. Please forgive my ignorance but I'm just wondering why the meth I get from one dealer is solid little shards and the meth from another dealer is much more wet, less solid and mushy like? They both seem to have approximately the same effect but the nice solid little shards are much easier to handle, weigh etc.

Is one better quality than the other? Have they been made differently? Different ingredients? Should I be going with one of these dealers over the other? Or is there really no difference?

Thanks for any advice.
