Hippo vs rhino

Full grown male hippo vs full grown male whit rhinoceros.
Takes place in African planes. 
There's a pool of water nearby where the hippo can dip in twice and can only stay in for 5 minutes. The rhino may drink from the water only twice.

I'd say The Hippo. The Rhino has bad eyesight, whilst The Hippo has a very powerful jaw-bite, which can easily break Water-Melons. They can also weigh more than a Rhino. 

If they start apart, I'd give it to the rhino because of the damage the horn will do on the charge. But the real winner of this will be the lion or croc that comes upon the two.

The Hippo wins.

I'm seeing some posts saying hippo wins. Im seeing some say rhinos wins. Anyone care to explain why or how?

The average bull hippo weights around 1.5 to 1.8 ton, but older speciments have reached twice that weight. 
 
The average rhino weights somewhere around 3.5 ton (White rhino, most populous), 0.8 to 1.6 ton (Black rhino), 2.5 to 3.2 ton (Indian), 0.9 to 2 ton (Java, uncertain) and around 700kg for the Sumatran rhino. 
 
I base my preference on the force of impact the tip(s) of the rhinos horns are going to make when 30km/h Hippo collides with a 50km/h rhino. Open mouth and fangs arent goign to do you much good then.
