yeah, the LMTs seem to be at the bottom end of the bang for the buck. For the dollar, Medusas can't be beat. Neus aren't too bad either if you compare the price to LMTs, and the performance difference is minimal if anything.
CC Patrick gave a little rundown of the differences between slotted and slotless:

BTW: Medusas and Neus are both 4 pole slotted motors. Feigaos and LMTs are 2 pole slotless motors. I think Hackers are slotless 2 polers as well.
