I just got my Treegloo case and have had my Portenzo case for a couple weeks. I ordered the Portenzo first but then they were taking forever to fill orders so I ordered a Treegloo. Portenzo shipped first so I decided to keep both. I posted my review over in the long Portenzo thread a while ago for the Portenzo. This is a comparison of the two.
I like posting pictures, so i'll do that and talk a bit about it.
The Treegloo is a bit bigger than the Portenzo. Portenzo is on the left, Treegloo on the right.
The Treegloo feels thicker than the Portenzo.
Treegloo
The corners on the Portenzo are much better looking, much more curved. Portenzo left, Treegloo right.
The strap on the Portenzo is much tighter than the Treegloo, I don't think the Treegloo strap holds it down enough.
The Treegloo is very loose at many points, especially on the bend, it stays like this while sitting on the table. You can move the front cover back and forth very easily. It's very hard to do on a Portenzo.
The Portenzo is stays in this position all the time.
Both of them work very well as a smart case.
Overall I think the Portenzo is made with a lot more care and it feels much better.
The Treegloo just feels cheaper with the square corners and the cover feels more patted than the Portenzo. It was cheaper than the Portenzo, so I guess that's fair. It also feels heavier than the Portenzo.
One big issue with the Treegloo is that the iPad 2 doesn't stay in very well. If turned upside down it comes right out. I followed their instruction for putting it in the case, but it still not very sturdy. The Portenzo stays on very well when turned upside down and it's very easy to remove (once Portenzo sent me the correct way to remove it. Just push the back of the case and it comes right out). I would make a video, but I don't have a good camera and tripod.
Treegloo has been known for much better customer service than the Portenzo team in the past couple of weeks. Portenzo has had a lot of issues with not responding to customers right away or ever. Treegloo responds right away.
I had a dodocase for my iPad 1 and enjoyed it. I rate them Portenzo first, dodocase second, and Treegloo third. It's not a fair comparison since I don't have the dodocase for iPad 2.
Edit: I realize I typed Ipad in the title, I wish I could edit it to iPad. I know it doesn't really matter, but I hate making dumb errors. I'm sure there's more than one in this post.
