Being a person who has only ever owned stallions and mares (my first 2 
horses were stallions) and only ever will...I must confess to feeling 
differently about this questions.  This is not because I want to breed 
horses, but just because I find them to be more interesting riding partners.
Yes, geldings are more consistent performers.
Yes, geldings are more predictable.
However, I find that with mares and stallions you are required to build a 
one-to-one partnership before they will give you their all...and it is 
the building of that relationship that I find most rewarding about 
working with horses.
As to trying to be the herd boss...well...sometimes that doesn't work 
(especially if your full grown mare is already an "alpha" mare).  I have 
watched in pasture what it is that horses do to determine who is herd 
boss, and believe me...you don't want to get into that kind of discussion 
with an animal that outweighs you (what?? on average 5 to 1) by as much 
as a horse does.
I am very clear with all my horses, from the day that we meet (sometimes 
at birth) that _I_ am NOT a horse, and do NOT expect to be treated as 
such.  Alpha mares and stallions are not particularly willing to be 
"dominated" to build a partnership with these animals requires much more 
subtlety than domination.
And partnerships are not about domination anyway, they are about mutual 
give and take.  And mutual trust is the essential ingredient, with an 
emphasis on mutual.  Not only must you teach your horse to trust you, you 
much also learn to trust your horse.  Mares, being by nature rather 
upredictable, can be difficult to trust.
The time to give up on a partnership is when you determine that you will 
never trust your horse or that your horse will never trust you.  That's 
when the relationship has failed, and, as much as I hate to say it, you 
probably need to move on.

p.s.  I am not saying that everybody should go out an get a mare or a 
stallion; geldings are indeed, in general, much safer mounts.
