I can't disagree more.  I optimized my 5 element 20M yagi for F/B and 
SWR.  The difference between it and a 204BA stack on TX is nil.  On RX, 
the difference is night and day.  I can turn an unusuable frequency in to 
a runnable frequency with this antenna as compared to the stack of 
204BA's.  What did I lose by optimizing for F/B and bandwidth?  A few 
10ths of a DB in gain.  So what?  You cant hear a few 10ths of a DB. 

Now, in regards to the TH7 vs KT34XA.  Gee... I dont know.  Both are good 
antennas.  KT34XA has more gain and more potential pain.  Personally I 
like to put up an antenna and not think about it any more.  I've never 
heard of anyone taking apart a TH7 and putting it back together again 3 
times because it wouldn't work right.  I've heard this story twice in 
regards to a KT34XA.
