If I had a METLE no way would I swap it, premiums will come up for sale more often than an LE so can be replaced.
That''s really hard to answer as they are so different. IMO Metallica is more fun to play with mates, cranked up with a sub. However if your alone and wanted to play something a little deeper with more to do then WOZ is the game. I have MET R/C and WOZ RR, so no bias to one or the other just my 2 cents.
