As others have said, it mostly comes down to personal choice about the 
interface. The underlying "calculating engines" are the same. I'd 
suggest you get hold of MMANA and the free version of EZNEC and see what 
suits you best.

I'm very impressed by the accuracy of these tools, provided you can 
model the antenna and its environment reasonably completely. Take a look 
at the measured and modelled performance of a 20m Hexbeam on my web site 
- particularly the final two charts - and I think you'll agree that it's 
plenty accurate enough for amateur use:


If nothing else you'll learn an awful lot about antennas by "playing" 
with the modelling tools.
