I'm a bit slow in posting this, but I do have an update. After much deliberation I ended up getting the
MEC Gemini ES (shown here in my backyard).
The main tents I was considering along-side this model were the
MSR Hoop, the
MSR Hubba Hubba, and the
Black Diamond Mesa. Realistically, I was choosing between tents of similar quality and capability and expect I would have been well served by any.
However, when comparing the models I ended up with the Gemini ES because of the following (I think) advantages:
- Stronger, more stable pole configuration (as compared to the MSR designs)
- Most fabric vs. mesh, but with some flexibility as the fabric on the doors can be opened and rolled up leaving only the mesh
- Usable vestibule design (more rectangular than triangular) ... my daughter also liked the little windows
- Good vent design (vents are propped open when set up)
- More durable/waterproof bathtub floor
Mostly, I went for the one I thought would be the most bomb-proof and winter & storm capable of the group; the only real usability advantage I think is the vestibule design (over the Mesa especially).
That's not to say it wasn't without some trade-offs. Both the Hubba Hubba and the Mesa felt bigger inside (only the Mesa actually was a little bigger). I think this is primarily due to the use of mesh which opens things up. The other tents were also lighter (visually) so they might be nicer if you ended up spending time in them waiting out rainy days.
The other models also all had better inner pocket/storage designs than the Gemini. Only the Hubba Hubba had a noticeable weight advantage.
In fairness, I should note that I wasn't able to actually see the Hoop in person (I wasn't able to find it in stock when I finally got down to my final evaluations).
