I prefer the Powerglide over the Freewheel, and here is why. (On 03/09/2021 one wheel fell off. What a remarkable run I had w this. Buying a new powerglide, I luv this thing. International travel soon, and this is my carry on. ) Having examined the extendable handle on the Freewheel (which I first ordered and returned), I found it to be somewhat wobbly or not too secure in the base. For example, when I extended it, and jiggled it side to side a bit, it seemed to wobble in the bag a bit at the base, not rigidly secure. So, I felt like I needed to try the Powerglide, since it had two pole extendable handle, and I am glad I did. The Powerglide's handle was more secure to me than the Freewheel, and therefore seemed more durable or able to withstand more use over time (who knows?). Secondly, the zippers on the Powerglide seemed better than the Freewheel. I did not like the Freewheel zippers, and felt like they would cause me trouble. Third, the shoulder strap enclosure, which doubles as a protective back and bottom cover, so as to not get your back dirty when carrying it on your back, was a very very good addition. The Freewheel did not have this. Fourth, overall, compared to the Freewheel, the Powerglide seemed more professional (whatever that means, respectable???), more durable, better featured (the double bar ext handle, back cover dirt flap, bigger, better zippers, etc.). However, I preferred the weight of the Freewheel over the Powerglide. The Powerglide is heavier. I bought a Mountansmith backpack raincover for this, and got to use it today! It worked, and also I discovered that it was not so hard to carry the Powerglide on my left side using one strap. I only carried it a couple hundred feet. Not planning to carry it far at all on my back. If this was helpful, please give it a thumbs up. Then I know I did you right. Thank you, Patrick UPDATE 2015-09-14 ================ I just got back from a three month trip to Tanzania. I used this bag on my back, on the road (that were paved??), in taxis, on the planes, etc. It performed well and carried a lot of stuff. such as a projector, a heavy laptop with extended battery, cloths, radio, wireless speakers, etc. Kinda heavy on the back. But the general durability of this bag is good. I also used 3 tsa loop locks on the 3 zippers (thru the cloth loops) just to deter a hey "what's in here" hotel behind the desk thingy, for some employee tried it right in front of my eyes and would not stop even though I said, Hey get out of there! That's mine. You are not supposed to look in there! Then I put on the locks right there. I would definitely buy this bag again and have been trying to persuade my wife to get one! UPDATE August 18, 2016: Still going strong, using it every weekday for laptop, coat, 9x13 thick planner, long computer power chord, noise canceling over the ear headphones and case, tall coffee mug, tall water bottle, mini voice recorder, pens, etc. I have been thinking of putting this to a very tough test time, so I can break it and get another one in a new color. So, a couple of times I ran it over very bad broken sidewalk while I was returning to my automobile from my daily activities. Not sure if I will continue to do so. The wheels may become noisy or break.
