That copper spur is a nice tent. I have had good luck with the MSR hubba style tents (either the mesh, or solid versions, whichever you like). The MSR would be my reco.
I haven't used the tipi style so i cant comment on those. have always rolled with the backpacker style.
All the sierra designs tents Ive delt with have been a little wonky. Just doesnt seem like the design or the quality is on par with some of the other brands.
