I do have a few Lyson 6F boxes. They are OK. There are some local hobbyists who have 10F poly hives and they like them. The bees definitely have an easier time maintaining their climate inside, year-round, and do well in them.
For me, there is no substitute for the strength and durability of wood. Which is important when handling, moving, stacking with machinery (trucks, fork truck, and lifts). , and bears. Drop a poly box of bees and honey it chatters, blows apart, not salvageable, complete loss. Drop a wood box and can just pickup, restack, add a nail or screw and carry on. Bears rip into and destroy the poly effortlessly. Wood, they have to really work at it and usually resort to tipping the hive and rolling the boxes around until the frames fall out. Wood boxes survive bears and people. Poly do not.
