If for some reason you want a Lang for competetion, several teams cook on the 48 and have plenty of room.
I am fond of both the 48 and the 60 and would be looking at them if I ever decided to leave pellets (ain't gonna happen
).
WSMs are lighter and easier to tote around.
As you know, they put out great que.
Do you really want a new cooker just for competetion, which you have not experienced yet?
Or do you want to expand/upgrade your cookers for home use also.
Your decision, just some thoughts.
