The weaving of more heads certainly will help in smoother patterns. Less 
nozzles per head can be compensated by more passes and with that speed 
sacrifice but it doesn't compensate the weaving. I have not checked the 
number of passes and the resolution possible on the cheapest Epsons like 
the C86 but I do not expect that they are in the same quality class  the 
2200/2400 are in. So I suggest that having more heads for the same task 
can be a sensible thing.
