The problem with poplar (much like pine) is finishing. It tends to be blotchy like I think you can see in the pictures.
If you don't care about how it looks (I didn't for a shop toolchest) then it is a joy to work with. Planes really really well. Hard enough and strong enough (that chest is 20 years old and the drawer slides, poplar on maple, work great. Silky smooth feel to them).
