Just from the pics, those first two look very solid, gotta figure out what sort of case you're looking for. I personally prefer having a case with extra bags to carry around tip tools, chalk, towel, a polishers and brandisher, moose-head, table claw for resting cues, etc. Basically, I make sure that the equipment I use, especially on my cue, is MY equipment. I control it, I know it, I understand it and know it won't damage my cue or game.
I think the more you're involved with pool, the more you appreciate quality equipment. I started playing on bar tables, bars that had tables. Now, I'm only interested in going to pool halls, and the bar tables feel like a waste of time and money. The same is true about the little parts of the game. I may be overly paranoid or protective, but I don't even like using house chalk anymore. I use the stuff I bring, and leave chalk behind after it's too worn down so I'm not putting a blue ring on my ferrule.
To this end, find a case you like and one that suits your needs. It's part of the over-all experience, so I say make it count.
