Tool box help.. Quiet Glide Vs. Ballbearing...

So I am in the market for a top chest to match my Craftsman Ball Bearing bottom chest... I'm looking at this one I found at a badass deal, but not sure if I want it due to it being Quiet Glide...

What's your guys' experience with Quiet Glide? I know I won't have my heavy tools in there, and having the 9 small drawers will be nice, so Ball Bearing may not make that big of a difference.

Help me out guys...

I have Kennedy boxes with those type of slides, and it works just fine, even with heavy tools...

Well went back to get it, and got frustrated trying to figure out what to do..

Then I realized they had a 5 drawer one for $150 that was ball bearing..
No damage to it, open box, and I talked them down 10% and then got another 20% off with my Craftsman Club card!!

Only cost me $125

Ball bearing seems more durable than quiet glide
