They don't. All earth bound telescopes, optical or not, must deal with a number of issues.
But what do you mean by "better"? A radio telescope is better suited to pick up radio waves than an optical telescope, but an optical telescope is better for visible light. They each serve their purpose better than the other.
Telescopes that work grounded on Earth include optical telescopes, radio telescopes, and infrared telescopes. However, space telescopes, such as the Hubble Space Telescope, do not operate from the Earth's surface. Instead, they are placed in orbit to avoid the Earth's atmosphere, which can distort observations.
X-ray telescopes are used to study mainly the Sun, stars and supernovas. X-ray telescopes work better at very high altitudes on the Earth's surface.
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).

In space, there is no interference by Earth's atmosphere.
"Optical" simply means that they work with visible light - as opposed to other EM radiation (radio waves, x-rays, etc.); gravitational waves; etc.
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
Lower frequencies have an advantage over optical because radio waves are not dispersed by dust and suspended particles as lower frequency and low energy frequencies are (such as visible light) , so with those kind of instruments areas which cannot be seen with optical telescopes become detectable.
Their advantage - the reason to have space telescopes at all - is that they don't have to look through Earth's atmosphere. This lets them get a clear picture; it also lets them work at certain frequencies that don't reach Earth.
No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.
Well, let's see. When I'm driving through a thunderstorm or a blizzard, I can't see a thing on theroad ahead of me, but I can still listen to the radio just fine. So I'd say it's the radio telescope.
A: An optical device, such as a pair of field glasses or Opera glasses, designed for simultaneous use by both eyes and consisting of two small telescopes joined with a single focusing device.
