Get BOTH.
They really are two different boots. I've got the LLbean 16" hunting shoe as they are actually called and also the 16" Shnees with the insulation. I had first bought a pair of the Schnees 16" uninsulated but found the rubber and leather too stiff or a combo of that and found them uncomfortable on my ankles. I sent them back and got the insulated ones.
Insulated schnees are a great colder weather and or deep snow boot with great fit,comfort,durability, and traction.
LL bean is a really comfortable spring, summer, early fall boot type of boot. the leather is still thick yet plyable so it fells good but should still hold up really well. the rubber boot portion is softer for greater feel for stalking type of conditons. Traction is better than the large chain link tread style like on the lacrosse burly rubber knee boots but yeah it won't be as good as the schnees air bob type of bottoms.
So yeah two different boots. But to answer your question, get the tall insulated schnees.
