Any toilet experts out there?

We're looking at maintaining/upgrading/replacing the toilets in our home.  To do that to our existing units is easy enough, but it occurs to me that we might be able to find better engineered toilets if we shop around.  I'm aware, for example, that some toilets are advertised as being able to flush golf balls.  That's all very well if you want to flush golf balls, but we want to flush the more usual . . . ah . . . debris.  So, what does it best?

Can any of my readers recommend a particularly good make or model from their own experience?  A reasonably economical one would be good - we can't spend a fortune on it.  Solid gold toilets are right out!

Please let us know in Comments.  Thanks!
