I have cervical radiculopathy. Is artificial disc replacement better outcome then a fusion?

I am sorry to hear of your suffering.

The question you have asked is a really good and important one. This is increasing evidence to suggest that once conservative therapy has been exhausted, a cervical disc replacement may be a good alternative to a cervical fusion. Other options can include cervical decompression alone such as laminectomy or foraminotomy.

There are a lot of factors your surgeon will consider when advising on the best option for you. These include but are not limited to:

Patient factors

• The pattern of clinical symptoms eg severe neck pain vs arm pain alone, unilateral vs bilateral symptoms, cord compression and myelopathy vs radiculopathy alone
• Bone quality (osteoporosis)
• Patient's lifestyle (eg smoking status)
• Existing comorbidities
• Patient's preference

Radiological factors

• The extent of degenerative change present in the spine (spondylosis), which may suggest that there is limited or no movement at the particular spinal level of concern. Introducing movement to a non-mobile segment has the potential to exacerbate neck pain
• Factors that are generally included in the assessment of this include: ankylosis (stiffness of the spine), osteophyte formation, modic changes (bone oedema), facet joint disease and more
• Presence of instability

Surgeon factors

• Surgeon's training, experience with the various techniques and bias towards a certain procedure having better outcomes

There is still more to consider however you get the idea. It is not a simple decision. Nonetheless, it is important that you speak up and discuss the options. It is also within your rights to seek a second or even third opinion until you are satisfied. 

I hope this helps.
