I really like my muck boots. Have not tried other but cheapies so can not give a good opinion. Find what fits you best and has the insulation you want and try them.
Bought a pair of insulated Bogg boots a couple years ago. Best thing I ever did. They are pricey for rubber boots, but they are very comfortable. They are similar to muck boots, but the pair I bought have a better sole for walking than the mucks I have seen.
