I don't know if that first case is the actual case you have or not, but I can say of over 2 dozen cases we sold at the last shop I was working for, that particular Plano with "PillarLock" was easily one of the best bang for the buck cases going. We did stupid stuff (like stand on the closed case around the pillar sites) and it didn't crush. Don't get me wrong, it's a "cheap" case. (The materials and such.) But, it will more than protect a bow for hunting. (Wouldn't recommend it for airlines.)
Now, that second case I actually own. I bought it because it looked
impressive. (I also liked the way it took up less space to open.) The bad thing about it is that only certain bows really fit in it. You'll notice that there is no mention of being "parallel limb" friendly on that page (unlike the first case) and you will also notice that they have an old school short riser / long limb (non parallel limb) Jennings Buckmaster in the case. I use the case for my indoor target bow. (So, no parallel limbs.) However, I still had to modify the case to accept the length of the bow. (I took the "fat" rollers off of the clamps that actually hold the bow and dipped the metal pins in Plastidip so that I could actually run them through riser cutouts instead of over the limbs because they simply wouldn't reach that far on the bow.) One would definitely be needing to modify as such to even have a chance of a modern extreme parallel limb bow fitting in the case.
Just look at the user ratings between the two cases you pointed to there for an idea of what to expect.
If you're wanting something a bit more substantial without spending an arm and a leg, I've had my eye on this one...http://www.cabelas.c...0017&hasJS=true
I also sold quite a few of these...http://www.cabelas.c...0017&hasJS=true
... to folks with short, parallel limb bows. It's a nice space saver and has PillarLock all around.
If you ever want the end all for airline travel and the full deal... You're probably going to want to look at SKB or Americase.
