Can Earth Tiger man ever be with Earth Tiger woman? do elements make good or worse?

No because it is not succured that an Erath Tiger man is more dangrous

I think you may have conflicts due to stubbornness. Both your Chinese and Vedic/Western signs (Aquarius-Leo) have a tendency to be stubborn. You may also find that the Leo/Tiger may seem a little overbearing (bossy, willful, domineering), as the more gentle Rabbit seems easy to push around. As long as Rabbit doesn’t let resentments build and both learn to deal with conflict in a respectful and timely manner, you can overcome this.

Compatibility is based on personality types, life experiences, and shared goals, so astrology is only so useful. If you have similar values and a willingness to work with each other through conflict, then you have a strong chance of success.

Sorry, reply went under wrong post.

But Tiger-Tiger would have similar temperaments (stubbornness) and a similar desire to be in charge, so keep that in mind.
